Can't explain the stalling but very occasionally if I switch off and then try immediately to start up, it feels as if the engine won't turn over; clicks once and sort of locks. Turn the key off again and after a couple of seconds it cranks normally. Guess it's done it half a dozen times in 70,000kms. I'm not concerned about it.
I've had the same and a couple of times the ABS light will then stay on for quite a while, sometimes it will re-set while you are still riding, sometimes it needs to be re-started. I've also had the odometer/trip meter display "go out" after a "false start", it comes to life after you re-start the bike. Same again, nothing to be concerned about.
