it sounds like a cps to me. some are better than others. there a long discussion on here about them.

94.5 F250 Reg Cab 4x4 5 speed 4.10 276000 plus miles

97 F350 Crew Cab LB 4x4 5 speed 3.55 320000 plus miles (parts truck)

I had the dealer replace the cps under recall about 16 months ago, and then I replaced a grey one cps with a black one from auto zone 4 days ago, also when it dies it will not restart for while some where around 20 minutes or so.

the "new" gray cps sensors do still fail. just not as high of a fail rate. the good thing is they are alot cheaper then they used to be. check codes, if it's the cps sensor then there should be a code stored in the pcm. what kind of code reader are you using?
