Wierd issue with skidoo Mxz 500

Hey guys I have a 2001 Skidoo Mxz 500 that I am having issues with. The sled will run fine for about 15 mins then engine starts to bog down until it eventually shuts down. If you leave it sit for a little it will run fine again for a little. The other week I actually rode for about 10 miles without out it doing it, but I never gave the sled full throttle as soon as I did it started to bog down and died. I originally thought it was the stator, so I replaced that but it did not fix the issue. One of my friends suggested that the fuel pump could be bad. Any help would be greatly appreciated!

Thanks
