I'm new to the forums and hoping I'm in the right area. I'm hoping someone out there may be able to provide some guidance/suggestions, or have seen this before. I start my sled with no issues. I drive for about 4-5km and the engine stops, just as if you pressed the kill switch.  Then it starts up with no problems. I may go for a few feet to a a couple of hundred meters and then it happens again. This will happen a half a dozen times in 2 or 3 minutes. Then I can drive it for hours (rest of the day) without it happening again. Next day, same issue. Stops 10 minutes into the drive a few times and then runs without issue for the rest of the day. This pattern has repeated itself for this entire winter. 

 

I think I can rule out fuel issues because it runs fine after the initial hiccups. Same with spark. Any ideas?
