I have a 06 Polaris Sportsman 500HO EFI. When it get warm I am having a hard time keeping it running and starting it again after turning it off. I changede the spark plug and put high test gas in it and still am having the problem. any suggestions?

I finally figured out the problem with my Quad. The problem was a clogged fuel injector. I added Berryman's Fuel Injector to the gas and ran it for about 10 minutes very hard and it is running like the first day I got it. Thank God it was a $4 fix.

Check that your aluminum heat shields on your fuel tank are intact. They tend to disintegrate and fall off over time. I had the same problem and it turned out that the fuel in my tank and lines was getting warm from the engine and exhaust heat. It doesn't take a lot fo heat to start causing fuel vaporization and vapor lock issues. I lined the whole bottom of my tank with aluminum duct tape and it is now working fine.
