Pulser coils can also be a problem , they can open circuit with high temp sometimes, I dont know the specifics for your bike though, as in what they should measure at and what wire colours, but in this case and the case of the ig coil, why not see if its an ignition issue by watching for a spark at the plug when its playing up, better still make it jump a 6mm gap by fixing something into the HT cap and held steady at 6mm away from engine cylinder / head (keep fingers away though, use other means to hold it fixed)
