I have a 2013 sportsman 500ho with 500 miles on it. It runs great most of the time. It will idle at 1300-1400 rpm then randomly die. It will start back up fine then do it again.... Lots f power running down the trail but sometimes dies idling down steep terrain. Any ideas of where to look would be much appreciated

That did work. I had no idea about that saftey switch. I adjusted both of my sportsmans. Thanks for the advice
