possibly regulator, bypassed kill switch. will try regulator Thanks

Grandson has an Eton thunder 90cc that has no spark. It would run for about 5 minutes and then shut off just like turning off a switch. Now i can get no spark. I have replaced the Stator, CDI< COIL AND PLUG. hAVE RUN OUT OF THINGS TO TRY. Mechanics that i know are all stumped. All that has not been replaced would be the Resistor and Rectifier could one of these be the problem? Does anyone have any ideas? Thanks
