Because you say it starts perfectly fine without hesitation and is perfectly smooth I’m going out on a long limb and thinking maybe something related to the immobilizer system. I’m not sure about the Twins but on cars I’ve had in the past they would actually start and run for a few secs before the computer would shut it off because it wouldn’t see the transponder. I actually have a key that isn’t paired yet. I will give it a test for shits and giggles.

Edit: Oh never mind missed the part were you said it runs fine the second start.
