Long post but I need some help.
My 2016 Summit X 800 started going into limp mode and the check engine light comes on. It wasn’t full limp mode because it would run around 6500 RPM but no power. Shut the sled off and restart and it will run fine for a bit and then do it again. After it done it the first day I took it in to the shop and they put on the computer. The only thing that pulled up was park brake set. The park brake lever is broke off so I knew it had not been rode with the park brake on. What we did notice was the brake was not pushing the brake light switch back in. We took the sled back out this weekend and it had the same issue. It would go into limp mode. I removed the switch and rode it with it off the brake lever assembly and had same issue but with it off the sled would flash park brake set. I taped the switch to the off position and rode it that way as if it was still on the brake lever. Rode the sled and within minutes the check engine light comes on and it goes into limp mode. Like before shut it off and restart it will run great for a shot time and then does it again. I looked for codes on the display and it says no P codes.

Does anyone have an idea of what’s going on? I hate to take it to the dealer just yet because warranty was up last November

Stator.. usually they'll tend to act up after they heat up and throw a voltage code concerning the coils, but it's not a perfect world... stator test is pretty easy, and can be done without tearing half the sled apart...

Update that might help others with same problem

Turns out sled would still go into limp mode after I changed plugs. while it was in limp mode I was able to get a code to come up. the code was PO264. It is related to PTO injector. Took sled to dealer and the found a broken wire close to the injector. repaired wire. Rode the sled yesterday for several hours with no issues
