1985 country squire engine problem

Got the car from a freind who rebuilt it after the septine belt let loose and took out all the vital compnets of the car. Now the car only runs until it gets hot then sputters and dies, but it then restarts once it cools down. Any suggestions would be appreciated.

I presume it has a carbureted engine.
Before you start the car, remove the air cleaner cover. Start the car and look at the carb as it warms up.
Make sure the throttle blade is opening. If it isn't, likely the power wire for the electric choke was knocked off or severed when the belt let go.

it does have the carbed engine i forgot to add that earlier

If it has a carb then it must have a 351 as all the 302s had a throttle body EFI,if it has a carb it sounds like its the ignition module as when they go bad they will quit when getting hot and it should be mounted on the drivers side fender well. If it has a 302 with EFI it still can be a ignition module problem but its mounted to the distributor as they will act up when the motor warms up. Jeff
