Jeep wont turn over when warmed up.
So I started having this issue about a month ago and cannot seem to figure it out on my own. I have a 1988 Jeep Cherokee with the 4.0. When I start the Jeep all is well it drives great but if I let the Jeep warm up and turn it off it acts like it doesn't have enough power to turn the motor over. I have tested both the starter (Brand new) and the battery (Optima) and both are performing great. I really cant think of a reason the engine would get so much harder to turn over when hot that I have to let it cool to under 140 degrees before I can turn it over again. I am thinking a sensor of some sort but I don't even have an idea of where to start.
TLDR
Jeep wont start when hot/warmed up but runs fine and starts any other time.

Those were some of my first thoughts I have all new battery wires and wire to the starter, and it is a new starter as well since I thought the same thing about the old one when this first started. My grounds I pulled off and cleaned and reattached as well about 2 weeks ago thinking it might have been those.

OK I will try that tomorrow on my day off and see what happens. But I have tried this with multiple batteries so I don't know what the chances of having 3 different batteries not being able to do it could be.
