Not sure if this is related, but I purchased a 950 SP (new) 3 weeks ago. Rode home from dealership without issues. Went for a ride the following morning - Started the bike and it only run on idle for 2-3 seconds and then stalled by itself. Wasn't doing anything, the bike was idling and being on the side stand. Same thing happened when I started again - only more difficult to get the bike started. In the end I managed to leave the house by constantly playing with throttle and clutch, without some throttle the bike would have stalled, no questions asked. This issue vanished when the engine became warmer. Same thing happened the following morning... Maybe even with the engine warm the revs dropped in a strange way, but difficult to say if it just felt like that as I was getting used to a twin again after years on inline fours.
Took the bike to the dealer and in the end the issue in my case was a faulty air pressure sensor that gave wrong signals to the ECU (This is as much as I can describe with my technical knowledge). Got the bike back on Thursday and felt good when riding home. Fortunately had to leave for a business trip same day and only back next weekend, so will only know then if problem really was solved or not. Just in case this helps identifying any issues. Happy that the bike was looked after by Ducati Monza, at least they seem to be genuinely interested to find out what the issue was and get quick feedback from Ducati as well...
