I have an '07 S4RS, full DP Termi kit, and about 2500 miles on the odometer.  On about three occasions I have had it die on me, all three were under the exact same conditions:

Bike fully warmed up, in first gear, waiting to make a unprotected left turn under "sketchy" conditions if you know what I mean.  Since I must accelerate with authority in order to make the turn without becoming a road pizza under some truck I was blipping the throttle to keep the revs up.  Right about the time I decided to let the clutch lever out and haul some (_!_) the engine dies and there is a very brief noise that sounds like what happens when you hit the starter button with an engine already running.  The seems like the sound happens in the fraction of a second AFTER the engine dies.

The bike starts right up immediately every time.  So far I've not been run over.

I mentioned this to the service guy at the dealer in Scottsdale, AZ.  He was at a loss as to what it could be (probably thought I was one of those crazy customers with over active imaginations), but he ventured that perhaps the throttle blipping was confusing the ECU.

Me?  I have NO idea what it's all about.

The odd noise after the engine dies is likely due the engine turning backwards, when it does that it 'backdrives' the starter.

Possibly the bike is still a little lean at low throttle openings, makes 'em more likely to blow the fire out like that.

What does it idle at when fully warmed up?

That sounds like reasonable theory; probably the right one too.

Will have to check the warm-up idle speed.

That EXACT scenario is when my bike decided to poop out. I was assuming it was the heat. I live in Miami and stop and go traffic does not make the engine happy. I thought she just overheated, but she fired right back up. Thankfully it only happened once.

bump

Well my bike started stalling at idle more frequently, and the low speed performance was going from bad to worse.  Cruising through a large parking lot was a nightmare, heck, anything under about 28 mph was very erratic.

Took it to Scottsdale Ducati.  They check it out and fixed it in about 30 minutes.  Said the throttle position sensor needed adjustment, as well as a trigger something thingamajig in the ECU.

Runs like a champ now and idles just right.
