Default 1991 F150 stalls during warm up.
My 91 F150 with the fuel injected 302 just started stalling like clockwork. It happens within the first 5 mins after I start up. I travel approx. 8 blocks and when I stop at a stop sign and push the gas pedal it stalls. Then it acts as it has fuel sarvation, but eventually starts after trying it 5 or 6 times.

Without a code the best educated guess for me would be the TPS. Get your multimeter out and check the voltage. If it is the TPS then buy a good one, not a 10.00 POS from Autozone! I believe those have to be set up by running it through the range before driving. Or, it could be 1 of 50 different things... Pulling the error codes from the ecm is your best diagnostic tool.
