Hello my fellow Polaris gurus, I’m new to this forum and need some help w/ my 2017 Polaris Ranger 570 efi. So the other day I took a ride up hill on my block and into 5min in my ride I felt a loss of power for jus a few seconds and it went back to normal but as I kept heading up hill after a few min it started losing power again so as I pulled to the shoulder it completely stalled out and would not start back up. My battery is good, I’ve put a new spark plug which has good spark, checked fuel pressure, new air filter. It turns over and cranks but does not want to start. Tried tapping starter and spraying starter fluid, jumping it and theirs no check engine light or codes showing up, and checked all plugs and cables. Pleeeeaaaaaseee help me I’m cussing up a storm. Thanks

Probably never. I bought this utv from a tour company that shut down after covid started.

Sounds like a valve adjustment is needed.
