Hey everyone, I have been having running issues with my 2004 Sportsman 500 HO. I start it, but it will only run for about 5 seconds then it dies. The only way I can get it to start back up again is to flip the kill switch off then on again, but it still only runs for a short amount of time. I'm not too familiar with all the electronics on this unit, but it seems like its going to be an electrical issue or maybe some kind of a sensor? I did some research on this topic and apparently there was a recall on my ECM, so I bought a new one hoping it was the issue but no such luck. I also bypassed the kill switch and checked the throttle safety thing, but nothing fixed it. Any suggestions? Thanks in advance
