Alrighty folks since I'm not a mechanic but a redneck with tools here it goes.
'93 f-150 5.0 when it's cold starts right up runs just fine. Will run just fine until you shut it down...then you better have something to do for about 6 hours. If I try to crank it to start while hot, it'll wear the battery down trying. Leave it for few hours it's difficult but will start.
Ok what hasn't helped list:
New fuel filter, plug wires, plugs, map sensor, distributor cap and rotor. It's got 2 tanks one the fuel pumps was already bad. The other one went so new fuel pumps.
So what's left? Coil or if it's got one ignition control module?

Whan this happens, if it turns over slower than normal, then i would crawl under the truck with a hammer, and whack the starter a few times. If it starts, obviously bad starter. Seen this quite often in fords. If this doesn't work, I would still have the starter checked. Could be heat sink in the starter.
Well I forgot to mention new starter a year ago. It doesn't really turn slow but does seem like it's laboring more than cold.
The truck was my son's he gave it to me tired of fighting the non start after warm. He said was doing that before starter change, after was brand new.
Yep that was a thought I had, when changed out fuel pumps went ahead got all the grounds cleaned and checked. When we replaced starter he got new grounding wire, with new battery.
Doesn't sound like a starter problem. Maybe an injector or the fuel pressure regulator is leaking gas into the manifold, flooding it until the gas dissipates or runs past the rings. How's the oil smell?
Oil smells normal, no gas smell. Would it be a good test get it warmed up shut it down have helper spritz bit of starter fluid in intake. That tell me if it's fuel or fire?
That sure would tell you about a possible fuel issue, which is top on my thoughts. Or, you can check fuel pressure with a rented tool at an auto parts store. Good idea.
Check to see if it holds fuel pressure after shut down or if the pressure bleeds off quickly. I had this happen on my previous truck and it was leaky injectors. Using a spark tester that just installs between the plug and the wire would tell you if you have spark or not.
I've used the starter fluid test on engines that didn't have fuel, but I wouldn't expect it to do anything on an engine that's flooded. Texasguy's test with the pressure gauge sounds like a better way to go.
