Yesterday I.was riding my new to me 850 and went to turnaround on a trail I didn't want to go down. It was a tight turnaround and for some reason when I would pull forward and turn sharp before I would go backwards, it would die. Not just die, but the key would shut off on its own. I was real low on gas and thought it was maybe empty, but once It finally got turned around it took me 2 miles home. Is there some sort of strange safety switch that shuts the key off?? I wasn't on a big hill or anything, just turning around to miss a massive water hole. It would go in reverse just fine but when I would put it into low to rock forward it would kill as soon as I would give it throttle and off goes the key.
