So I went on a long ride yesterday and ran my 2014 sportsman 800 pretty hard. It performed great for most of the ride but then at one point it stalled, check engine light was on, and the cooling fan didn’t seem to be working. It started right back up no problem. No overheating light, just the check engine.

I Let it rest for awhile thinking it was just overheating. Started it up and it ran great again for a long time. Then it started having a hard time idling. It would stall if I let me thumb off the throttle completely. No big deal because it was still running great at speed and the check engine light wasn’t on. Surprisingly at the next stop the cooling fan was turning on again. Figured all was good again minus the rough idle.

Rode a bit longer and then the check engine light came on again. This time it was starting to spit and sputter, had major power loss, would stall at anything less than 1800-2000 rpm, cooling fan was only working here and there and it would not engage into 4 wheel drive.

By the end of the day I was just burin it back to the truck and it wasn’t easy. I cleaned it and started it up today. Sounded prefect, no check engine light, 4 wheel drive was engaging and it seemed to be idling ok. Decided to go for a ace ride to see what happened. Ran perfect for about 20 min before all the Same symptoms came back.

The check engine light is so vague and the symptoms so sporadic I don’t know where to begin. I checked all the fluids and everything looked good.

I like tinker on stuff myself but Where do I begin? Or is the answer to just take it to the shops.

Thanks in advance for any and all advice here.
