I have an '08 S4rt and it has died about 4 times with 1500 miles on it. I mostly have issues with the nuetral light not coming on and having to start it with the kickstand up and theclutch pulled in. Good times.

I have a '07 S4Rs w/ full Termi exhaust , DP ECU, Open Air Box and it hasn't stalled and it has 4200 miles on it....but my '08 1098 R stalls when it reaches 219 degrees .

It starts right back up , but it is dangerous because it usually only happens in stop and go traffic .

It's very frustrating. My Ducati Tech told me that Ducati has there bikes setup to stall at 240 degrees so as to not damage the engine ...but I've not seen that in the manual and I don't think that is very safe for the rider of the bike if you were riding and the bike got that hot and just quit !   Dolph

I have a 696 and the last two night have been around 65 degree F. It never experience this low temperature since I got it. Both nights it died on the first try but started back up just fine. I did fully turn on the fast idle lever prior to starting it. 

Well, make tonight the third time it done this

I have an S4Rt with 12,000km on it and it still dies if I don't warm it up in a certain way. This is what I've noticed.

When starting the S4Rt from cold it will fast idle, then enter a "rolling Idle" state until it hits 50 to 60 degres C, depending on the day. If l allow the rolling idle to complete and then ride off, the bike will not stall

Now, if I'm in a hurry and I don't complete the rolling idle sequence before I ride off, I have to be very carefull when coming to a stop as the engine will likely die. I can combat this by selecting neutral before I come to a stop. Once in neutral the rolling idle sequence will continue. This can happen a number of times until the bike warms up enough.

I have also found that if I take off before the rolling idle sequence finishes and ride for a while, when I next come to a stop, even if the engine is at a good temperature, it will still want to continue the rolling idle sequence for a couple of seconds until the ECU detects that all is good. I have to watch for stall at this point too but then it's happy.

So I've learn't to adapt to this, either warm it up fully, or just watch out the first couple of stops (or off throttle applications) until the rolling idle sequence has finished. Then all is good.

BTW, the S4Rt is stock except for a Termi shorty.

My Rs has full Ti Arrow system with DP ECU & open airbox, so its no assurance that the ECU will fix the problem.

Look at it this way - the occassional embarrassment helps to keep you from feeling too cool on your sweet ride.  At least for me it never seems to represent a safety issue nor does the bike ever have any problem starting right back up.

I've had an '05 S2R for about two months and have had two stalls, both when cold.  One happened on a quick run to the gas station after its first wash, down shifted and it died.  I think that one was related to the cold idle issue mentioned above.  It happened again yesterday.  I blipped the throttle with the clutch in leaving a parking lot to get a cage's attention and it died as soon as I brought the throttle down.  BTW, it has no cat and cored stock cans.  Glad I'm not the only one....

In my mind (maybe only there) it has something to do with the constant rpm - the engine will get lazy and not be awake when it must perform differently. I might very well be wrong, but I have had similar experiences with cars. Well, just a thought.
If I'm way off  +1 to what the others are saying

Mine has happened hot and cold (same unit - 05 S2R).  Does yours make a 'click' sound and then die?  Mine seems like an ignition cut-out: she just clicks and stops dead.  No faltering, stumbling, etc.  Idling fine......click...stall.  At least it's a very infrequent happening.

I have the 07 S4RT as well. From new had that stalling issue occasionally with standard exhaust and ECU.... 

Then put on Zards with the DP ECU and now runs like F18 jet fighter....  [moto]

I haven't notice a clicking sound, but I'll keep my ears open.  Both times it started right back up.

I called up my dealer and they say it's because the engine is still very tight and breaking in.

But it still bothers me because it have trouble starting on the first, alot of time second, tries whenever it is below 75 degree f out. On top of that as soon as the engine cease I heard a loud pop as if someone just open a champagne bottle. Sounds like a late detonation. Any clue on this weird pop?

Don't accept that anwer from your dealer.  Stalling is not normal.  The "pop" is probably a back fire in the air box.
The cause is probably either reversed coil wires or a minor adjustment.

UPDATE: Since I wrote this I have had the 12,000 km service done at which they also "tuned" it. I tell you, it's a much better beast now. The rolling throttle is still there, but not as pronounced, and it seems to get to it's normal idle a lot quicker. I can take off cold without fear of it stalling when stopping. I think I'm getting slightly better economy as well, but I'll let you know for sure after I give it a couple of fills.  [moto]

alright,... my scooter went in for the 600 mile service two weeks ago. The mech said everything is fine with the bike. Since then, my scooter haven't stalled or pop any champagne bottle while starting up in the even colder temp now. It still does hesitate a little at start up but no stalling. The mech must of adjusted something since I did mention the starting trouble to him. I did notice my idle speed is at ~1300rpm now where it was at ~1200rpm...hmmm

For me, this usually happens shortly after starting my bike probably within a minute or so. and I so i thought about the things that I could be doing that might cause it.. I find that this usually happens when I rev the engine w/the clutch pulled in (...what?! I cant help it.. it just sounds so good) just before turning it off--maybe that causes extra gas to go in to the cylinders  i dont know, but im guessing it somehow affects the air/fuel mixture when the bike is turned back on later and therefore causing the engine to die.. since I've made a conscious effort not to rev the bike right before turning it off I surprisingly havent had the bike die on me again... just a theory...
