It seems to me that if the stator was going bad or completely failed, you would have battery charge problems, as the stator (alternator) is what charges and maintains the charge of the battery along with the voltage regulator. I doubt the stator. Likely the coil or CDI.
Are you having any battery problems, had to recharge the battery? Did you check its voltage at idle, off and at higher rpms?
When the engine quits, do you have any spark? weak spark? no spark at all?
The plug wire, mine at least, has a cap/boot at both ends and is able to be removed from the plug and the coil. Check both ends, and apply dielectric grease.
