2014 pro randomly dieing

I just got back from the Snowies and my sled was acting up out there. About mid-week it started to die occasionally, it always seemed to at the worst time, naturally. It would be after I would be going slow, around a meadow or lake looking for a line through the trees. Once I found a line I would start up, wide open, and make it about 2-3 sled lengths and it would die like you hit the kill switch, as soon as you stopped it would fire up first pull. The kill switch is moved so I'm not hitting that, we unhooked the tether, and checked the connectors by the steering post. We also changed spark plugs. It has a Silber turbo and reflashed stock ecu, which worked last year when I rode it. What/where else do you guys think I should check? Thanks, Clint

I had adjusted it when I was out west and to start with when I turned all the way to right it would die. I lengthened it back out and it wouldn't die but maybe I didn't go far enough. I can't believe it never crossed my mind to try to lengthen it more......:der: actually I can believe that, lol. Thanks, Clint
