2008 Polaris Ranger 700 XP 4x4 EFI
I have a 2006 700 EFI that Boggs down/ Loses power when it gets warm. Another shop replaced the spark plugs, wires, and throttle cable for this problem a couple months ago. But it is doing it again so they brought it to me. I took it for a test drive, and once it got warm it would backfire, ping and eventually die. I drove it again and found that the fuel pressure was falling on its face while it was doing that. So i replaced the entire fuel tank/pump assembly with a new one from Polaris. Cleaned out the fuel line, and checked the spark plugs for proper gap one was to tight so gapped and reinstalled. Took it out on a test drive and after it warmed up it loses power, but it no longer backfires, pings or dies, just looses power and I crawl back to the shop. The Fuel pressure stays in spec the whole time. Also i doubt this has anything to do with it but i did just put a new primary, secondary clutch and belt on it a week ago. Any lead here would be helpful.
