I have a 2004 Sportsman 500 HO ATP with less than 600hrs that has been flawless since I purchased. I've only had to replace 1 CV boot and a starter relay. The rear foot brake rusted so I disconnected it but not hindering performance. I use this for travel to/from the woods and game retrieval during hunting season. Stored indoors. About a month ago I was riding around and when I went to idle the engine stalled. I tried to restart and it acted as though it was fuel starved. Tried to fire but backfired or would not stay running. Very hot day 100+ and thought I may have vapor lock. Let it sit a couple minutes and it started it up and ran another 1/4 mile before I stopped to check a trail camera. Engine died and would not restart with same symptoms. Few minutes later it restarted and I drove it home 1 mile with no issue. Full fuel tank, checked the fuel cap to make sure it was not to tight and getting a vacuum lock. Later it started and I was able to load and trailer home. Replaced the fuel filter with a larger see through filter and replaced the fuel pump when the filter did not solve the issue. Disconnecting the fuel lines replacing the pump produced good flow but have not pulled the line off the carb to see how the fuel pump is pushing to the carb. The behavior seems to be dry carb. Once the bowl fills up it runs until dry.
Before I pull the carb for a rebuild/clean, anyone have any suggestions besides checking the new pump is working and fuel is getting to the carb?
Thanks in advance.
