I have a 2004 Polaris RMK Magnum 500. I use it just about every day on the ranch. Great utility.

Has been running great and recently changed oil, filter and air filter about month and a half ago. Started running crappy a few days ago so in went a new plug. Still the same.

It runs fine for about two minuts then it missed if given power. On level ground slow speed it is fine. Acts like fuel filter but I have not found that yet.

Any ideas.

If you have not changed your fuel filter in a long time I would definetly do that first.
If that does not remedy your problem your carburetor may need a cleaning or overhaul.
Also I would suspect weak spark, Plug lead failing or your stator failing.
