I have a 1977 Ford Bronco with a 302. Recently I warmed up the Bronco in the morning waiting for the engine to lower it's idle. Unfortunatly, I went inside and when I returned 15 min later the vehicle was idling at a high RPM rate.
I drove the vehicle about 500 yards when the engine stalled like it was out of gas. I vented the radiator and loosened the gas cap. The truck started and it drove like new.
The next day, once the vehicle heated up it again stalled twice. I made it to work and then after work on the drive home it stalled every 1000 feet. I wait 3-5 minutes and it would start and then 1000 yards later it would stall again.
I was thinking it may be a fouled fuel filter but I can't get why it stalls like it is out of gas. Is there anything on the 302 that will cut of gas supply??? or is it fouled distributor?????
Head Gasket is fine. I know it needs a new Thermostat but I didnt think that the thermostat could cause the engine to stall. I am sure it is some componant that is getting overheated, I just cant figure out what it is.
