I am fairly new to jetskis and have a 92 waverunner 3 that keeps losing spark. It will start and run fine first thing and continue running fine untill I shut it down. It does not die on its own. Once shut down it loses spark for awhile. The stator ohms out good and messing with the wiring in the electical box sometimes works, sometimes doesnt. Unhooking the kill switch has no effect. Does anyone have any advice before I start throwing parts at it?
