hey guys I'm New to this and actually trying to help my husband. he has a 1971 ford f100 completely rebuilt with a 390 engine. lately, he's been having some trouble keeping the truck running while it's idling. the truck starts up every time without any problems, but once it warms up for a minute or two it completely dies. he's never had this problem before. he's redone all the wiring, coils, spark plugs, ignition switch, he's cleaned the distributor and carburetor. and at this point he is completely lost. he built the truck himself, so he knows it very well. if someone could help and guide us in the right direction, it would be greatly appreciated.

 

If the truck still has a points ignition distributor, install a new condenser.
