I'd say it's one of two things (both of which I've experienced with similar symptoms) - either a problem with the injection pump mounting, causing the pump to twist slightly and alter the timing, or a plugged air filter causing early stages of runaway. Both are serious issues, so check 'em both - ie: check those inj. pump bolts, and check your air filter...
