2012 rzr 800s as soon as I turn on the motor engine light comes on and will not rev up, and it sounds like a up and down sound. phone was charging and it sounded like the phone was going from plugged in to not plugged in. I took the phone and chord out of the picture and it still does it. aftr I ride a little it goes away. like something is wet. it can be running fine and I will shut it off and restart and it does it again. where do I start to troubleshoot?
