i am not for sure but maybe the coil.
my friends toy would die after running for a while a normal temp. so we took the coil off my toy and tried it on his and seemed to work fine after that. i have also heard of the dis. doing the same thing.

just a shot

Does it crank but not start, or does it not crank at all, or...?
