    2004 Polaris Sportsman 500 HO fuel delivery problems.

    I use my Sportsman primarily for surveying. Not too hard on the machine, mostly putting around at low speed. However, when I run it hard, throttle wide open alot, on a trail ride, it runs great for about an hour. After that, the only way I can keep it runing is to pull on the choke. If I let it rest for an hour or so, I can get about 10 good minutes out of it until if chokes out. If I let it sit overnight, then it is good for an hour or so. This only happens when I run it hard. Day to day survey work never causes this problem. I replaced the fuel filter the other day with no noticeable change.
