    Truck stalling

    I just got a f150 v8 1991. It's definitely a project truck. It's got some blow by but runs fine. I drove it 140 miles home it ran fine. The other day I drove it around 6miles and it died at a stop light, but fired right up. I drove another 200ft and it died at the next light. Took a few turns of the key to start. I drove a few miles back home and it died again on the way. It always fired back up. When I got home I let it idle in the driveway for around 20 minutes and it ran fine? No dash lights came on. Any ideas? I changed the oil after wards and flushed the radiator. Could it be a vaccum leak? Heard that was common with these. Thanks, Jeremy.

    You said a project so has it been sitting for a while ? I would change the fuel filter and check plugs and dist. cap,rotor! Also if you suspect vaccum leak and can't find it check vaccum booster for the breaks!! Good luck!
