I posted this on advrider and got 1 reply that said take it to a dealer to read codes and not enough info so here we go

Thought I had the issue solved and now I need help. details: 2019 1290 SAS 63,000 miles. I have owned it for 53,000 of those miles.

Last week while riding my engine just cut out, no warnings on the dash, no stuttering no symptoms at all. Coast to the shoulder and try to restart the bike, it spins the starter but no fire-turn bike off/on same issue. Next day, I drain the gas and boom the bike refires and no issues for about the next 400 miles and a couple tanks of gas. I figured it was bad gas and didnt think anymore about it.

FF to Sunday and bike dies again, same issue no warnings and no restart.

I have read that the SuperDuke (a sister bike to the adventure bike) had some similar issue with connections in the killswitch area-gunna try to look into that

Any other common issues or thoughts?

I have read that there is a connector that I can then plug an OBDII in-is this accurate? But also that you need $$$$ readers

Id be checkin fuel pump and if its holding/making pressure. I dont know anything about a road bike. But have seen a handfull of 350's do weird shit when the pump is getting iffy

I think I’ve narrowed it down to a faulty killswitch or the crankshaft position sensor.

Funny thing is after sitting for 2 days it fired right up. I’ve ridden it like 50 miles no issues.

I have an appt Tuesday for service to pull codes and see if there’s something not flashing on the dash.

Otherwise I’ll keep running it and keep in cell service range to catch an Uber home if needed haha

I know of a kx450x that had a wire break in the harness for the crank position sensor. Random no starts, always in fucked up places.

Most every shop in the valley got to see that bike and nobody could fix it. Was down for near a year before somebody figured it out..

Guess I can update this. Went to the dealer last tuesday to pull codes and see if there was something hidden. They pulled some soft codes relating to low battery which was from the stator going out about 2 months ago.

they had no new ideas except that the ECU pulled back one of the faulty codes and shut down thinking it was a current issue.

Bike has not had a problem, but it was down 2 days for a new tire end of last week and now again last night because I have to patch said tire.

speaking on that, what are peoples feeling about a patched tire. I would be plugging this one, almost dead nuts center rear. my concern is that this bike has lots of horsetorques. I have a new rear coming in as backup, just hard to throw away a $250 tire with like 400 miles on it when they normally last like 6,000-8,000 miles
