I have a 2008 M8 and the engine cuts out(like hitting the kill switch) while letting off the throttle, once I let all the way off it comes right back on and acts like it is stuck in "high gear". Again once I let the rpms get back to normal idle and get going again it is fine. It randomly happens every 5-10 minutes. Any suggestions on things to check? The tss has already been disconnected.

Stuck in high gear? As in you stop the snowmobile and the idle is high? Or it just keeps moving forward and won't come to a stop?

Check throttle function from cables to butterflies...make sure they are closing. Could be a lean condition from an air leak also.

Update if anyone else had this problem. The belt that was on the sled was getting worn out and too narrow. Picked up a new belt for this season and it hasn't happened again.
