I’ve got a 2013 Polaris RMK 800 with 1900 miles, it’s got a SLP stage 3 kit, and high compression head. Around 2 years ago the sled would throw the DET code, flash the yellow check engine light and the sled would turn off. This would happen during the top end of the throttle and generally in the powder. This happened once every couple rides and would fire right back up first pull. Recently it’s thrown the code the past two rides while in the powder(7 times the last ride). Always on top end of the throttle. I’ve put in new spark plugs, and took it up the road where it did the same thing. Took out the gas in the tank and replaced it with a different 91-non eth. Took it up the road and it threw the code again. It’s got the ability to tune the engine electronically. Any help on next steps would be greatly appreciated
