Slow/No cranking power when HOT

Slow/No cranking power when HOT
I have a 1996 F250 W/ 7.5l. Truck starts fine, and will drive long distance with no adverse conditions , period! However, After ~ 5-10min running, If/when I shut it off and attempt re-starting, it acts as if battery is low I.E. barely or will not crank. Let it sit for an hour or so, it will start.
It will start repeatedly, if I do not allow it to warm up.
I have replaced, battery, starter solenoid and starter.
My battery voltage reading 13+ ( when condition exists!! ) charging voltage is 14+ while running ( before and after issue occurs )
Checked battery cables, OK.
I can start and drive to work, as long as I can let it sit for a few hours, before attempting to start.
Also, when condition exists, a jump or charger start, does not work.
Great truck!! Need help please. Thanks guy's...

Was it doing this before you replaced everything? I'd check all of the cable connections, after that I guess just start narrowing down the list of checks starting with things you just replaced. Load test the battery, have the starter checked also. A lot of these reman units are junk right out of the box.

Yes, The reason for replacing battery, Starter and Starter Solenoid was due to this issue. I have noticed over time, this issue cropping up. For instance, If/when I was towing on hills, I would occasionally get an engine light, then, when back on flat pavement for awhile, it would go out. I always wrote it off, as a O2 sensor acting up.
If I would stop to get fuel, upon re-starting the truck it would labor ( same way, like it was low battery. ), but at least it would start. So , this condition slowly got worse. I'm going to get an analog meter and see if there are any stored codes. As mentioned, I have checked all wires and charging system, all good. FYI, I'm am a trained mech. but, lacking certain diagnostic tools at home. Hoping someone else has seen this.
