Start it up and take off and about 30 seconds into running youll get a solid beep for about 3 seconds then it goes off , it seemed to be running fine maybe a slight miss a idle but not sure if thats even related since maybe i just noticed it, then after a few times of moving areas and it doing it I was making a longer run and it took me off pad on its own and shut down to where it would only do about 6mph. So after a few minutes of wondering what we were going to do since we were 15 miles from a ramp I hit the throttle and it jumped up on pad and I ran it back to the ramp easy. Any input ?TIA
