Bought a used 2015 Ace 570 end of last year rode it a few times in the yard this winter. Got it out today to ride around and it stalls out at around 12-15 mph every time. The check engine light comes on the machine shuts down. No flashing codes on the check engine light just a steady light on. I shut it off and turn it back on and it's fine no engine light runs fine back to 15 mph and stalls out. I know theres a seatbelt sensor I tried with it clicked in and out same issue both times. Is that sensor messed up or corroded and where is it located. Any help would be greatly appreciated.
