First thing you need to do is see if its loosing spark. The only way you'll be able to do this is when it acts up. Get it hot, get it to fail, and then check for spark. If you have spark then you can rule out electrical if not then time to go further.

Get a manual if you don't have one. Get it to fail and perform stator and other electrical tests outlined in manual but test results will only be valuable when the failure occurs so it may take a few tries.

Best of luck!
