I bought a new sportsman 570 eps first of the year. I have 215 miles on it. While riding last night in 3 feet deep of snow and my atv shut off twice. I thought it was just me bumping the key or something but my buddy bought a 570 tour and his shut off 4 times.it is dangerous because it usually happens when climbing a hill and you are committed.Im wondering if since they moved the battery into the front of the frame uncovered it is shorting out because when I went to restart it, the headlight dimed down and the starter just clicked. Waited 3 second s and it restarted and away I went. It is very confusing because I know if I take it to the dealer they will keep it two weeks n say they cant find anything wrong with it.My buddys is doing it more than mine. I wonder if they have a bulletin or something to let us know a fix for this problem.Maybe the cooling fan is getting pluged with snow making the safety overheat sensor shutting it off . Thanks for the replys.
