That'll be what it is then, an erratic neutral light switch, not the side stand switch. With the side stand up the a faulty neutral light is out of the equation.

I guess your original problem was that the vibrations of the engine when it started caused the switch to open, maybe just for a millisecond, the bike thought it was in gear and cut the engine because it was on the side stand. If on your travels the neutral light eventually fails completely, then all that will happen is you'll be able to start the bike in gear without the clutch in (assuming the stand is up) with the stand down of course it won't start at all.

Good luck with the rest of your trip.
