    Not a big motorcycle buff but sounds like to me it may be a spark issue. Spark plugs tend to fail if they can't get the right amount of amps. Pull your spark plugs one at a time and hook your Spark tester to it and see what's going on. Check for weak spark. Test your coil also. Those tend to not work correctly after heating up once they get old.
