great question!

from the beginning i felt this was an ignition problem and not fuel, i did not state that here because i didnt want to skew the replies. it felt like someone was pulling the coil wire on and off or pulled the coil wire completely. after replacing the pump and spider i felt capt's fuel information was incorrect and went back to my gut telling that it was ignition. i beat the crap out of the ignition switch and the car never faltered so i felt it was not the problem. on the way home one day i popped into autozone and picked up a coil and ignition module, when the car died i pulled off the road and replaced the ignition module and the car died 50 feet later, then i put the coil on and the car ran good the rest of the way home and i thought it was fixed but it died the next morning after warm up.

when all is said and done i now had a new fuel system and new ignition system minus the crank sensor. my son and i did a few internet searches for "stalls no code" and 9 out of 10 cures were crank sensor. so we picked up a crank sensor and when we removed the old crank sensor it came out in 3 pieces and had a hole in the end of it. it took me 20 minutes to figure out how to dig it out of the timing cover. as soon as we saw it we new it had to be the problem.

i can not for the life of me understand how a crank sensor in this condition did not set a code. after installing the new crank sensor i got a P0300 and will take the truck down in a few days to get a case relearn done and that will remove the code. the truck runs perfectly, it positively does not stall or falter anymore and that 55 psi after 10 minutes is bullsh*t.

i hope i answered your question

 

Thanks for the thorough followup. All good info which will benefit others.
