Answer
Hello Jeff,

   There are a few things that can cause this problem, but it is generally either a problem with heat in the fuel system, or the ignition system. Here is what I recomend. Replace the coil, and make sure all wires are tight. Use Champion Powersport spark plugs. Try a small amount of STP in your gas. Be sure to use decent oil, like Amsoil. Hope this helps, if you have any trouble let me know. Good luck with thr sled! --Arcticatman
