I have a 1991 ford f150 5.8l 4wd. When the temperature is below maybe 80 degree's outside, my truck will not stay running. It will stall out going down the road. I do not have a lot of money keep replacing parts until i find the problem. Truck runs awesome when it is hot out. Can anyone here tell what the most likely cause of this problem is? I greatly appreciate the help.

A good place to start would be to pull codes.
