i almost wonder if one of his main systems is going out specifically his dizzy. sounds like an issues i had when my dizzy went bad all 5 times. they either crap out or they go speratically only giving spark when they care. but really it was almost like a rev limiter. start there. test all major system if you can. do a compression check all that jazz make sure he doesnt have a dead hole either.
