Hello, I am having problems with my sportsman 700 EFI. When I ride it for about and hour it wants to lose power and when you give it full throttle it barly wants to go. It will chug and sputter. But if I leave it sit for a while, it rides like normal. This has happened a couple of times.

Please help
And Thanks

 

I'm thinking it sounds like the fuel pump. Do a search, also read the sticky above.

 

Is the vent clogged? Maybe the fuel pump is creating such a vacuum in the tank that it can't provide the fuel pressure needed. Let's hope the tank doesn't implode, I've seen it with cars.

 

Yup like stated by lovmudd...I think it's the fuel pump going as well...

Thanks for the help guys!! I will go out and get a new fuel pump and install it. It sounds like the right solution.
