Truck cranking, but not starting when engine is hot. on 1995 Isuzu Pickup

Any suggestions for my 95 isuzu pickup truck that will crank, but has trouble starting only when engine is hot? No trouble starting when engine has cooled down. Truck runs good once it does start.

Sometimes the ignition control module or other components will heat up and fail, then once they cool down they will work again, Need to have a tech put a meter on this after it heats up and won't start.
