The "crank trigger" also known as the crankshaft position sensor is the magnetic pick up located in the left side crankcase cover.

OK, I didn't catch on that there was a ~1 year gap in this saga.

Did you replace the relays?

did you wiggle the wiring harness as Howie suggested?

After it dies and won't restart, do you hear the fuel pump priming at key-on?

Thanks for the reply. No, I have not yet replaced the relays --that's on the shopping list.

I did not get down to the harness, but moving the bars had no effect. Time before last I was riding at night and the lights/dash were clearly on when it died. Riding around town with a number of corners and bar movement had no effect. Time before last it died in a straight line and last time died while warming up in the driveway with no movement whatsoever.

Most times when I'm attempting to start, I don't key-off each time, just wait a bit and hit the starter. I'll be sure to key off/on to test. Last time I tried to start it, I did give it some throttle to see if that would help. It did not seem to, but I could definitely smell gas.

Gotcha. Thank you.

I have to say that it does sound similar to a problem I had with a broken wire in the wiring harness of my 2000 M900 - runs great except for when it doesn't run at all.  In my case, the broken fuel pump wire would only separate with the handlebar turned to the left AND when accelerating.  Is the wiring harness cinched up a bit too tight, perhaps?  Given the straight-line nature of the failure, maybe it's a bad electrical connection.  Have you checked those?

Thanks for the info. It's a (slow) work in progress.

I got the plastics off to get to the relay and removed it. Auto parts store gave me a "match" that didn't work, so will wait on the part from Ducati.

In the meantime I'll start poking and prodding more wires now that they're exposed.

Went to do some more testing with fairings removed and fuel pump didn't power up with key on. Repeatable multiple times, so I figured it finally failed. Walked by 20 minutes later and had to give it another go and it spun up like it should 

So now I have fuel pump relay on order, in addition to starter relay. Figured they're old enough by now, may as well just replace the lot.

Thanks again for the help.

Just wanted to update in case anyone was following. Issue appears to have been the fuel pump relay. Wasn't able to hear while on the roadside, but in the garage when it began failing it was obvious that the relay was not buzzing when it should.

Almost forgot how fun this bike is. Thanks to all for the pointers.
