Alright, I have a 86 Quadsport 230s. I have done a bunch of things to it, but my most recent problem is that I had it running great and just one day it started cutting out while driving then it would come right back on. Then eventually it starting cutting out more often. Until now it has zero spark at all. I have checked out all of the components and they seem to all by within specs. Anybody know what could possibly get warmed up and quit working completely?? Almost to the point where I have to take it to a shop to troubleshoot more.

Thanks any info could help.
