my friend had the same problem on his 94 f150 5.0 and when he would start it it would die. so he was told to replace the idle motor which was like $100, that didnt work and then now he found out his fuel pumps were bad so he replaced them. but he thinks the pumps are not the problem. he had his engine recently rebuilt 1 year ago. i think he said that the truck still does it once in a while.
I had the same problem with my 89 F-150--5.0.I replaced the idle control valve.Before i replaced it,the motor sounded like it was coming through the hood.I bought the part from Autowarehouse.com--suppose to be genuine Ford but it did not have motorcraft stamped on it.I paid extra did they get me?
