2017 Mule Pro-fx never had any problems until now. It was running great one day and then the next day it would not start. No check engine lights, no codes that I have found. I have tried leaving battery disconnected for 30 mins, nothing worked. Finally, since I knew it had spark and fuel pump was running, I tried a little shot of starter fluid and it fired up immediately and ran fine. I let it warm up and drove it a little with no problems. I even killed it and restarted it, and everything was fine. come back the next day and same situation, no start. Not sure where to begin, If anyone could help point me in the right direction I would appreciate it !!!
