Start with the basics. New spark plugs, check all your connections for moisture and corrosion, check kill switch, tether, throttle safety switch. Make sure your plug wires are good, you can unscrew the cap, trim back the wire about 1/4", screw the cap back on. If everything checks out, and you still have troubles, start looking at coils, cdi and stator.

test your stator first along with the throttle over ride system. you need a quality mulimeter to test the stator and you can do a quick tors bypass for testing purposes.

could also be as simple as a rusted flywheel. your battery is fully charged and in good condition? any signs of critters gnawing on wires?

I've done most of the basics and the tors bypass. I'll start this weekend with looking at the wires down below and checking the flywheel rust. Is there a way to test the cdi box?
