What does the temp gauge show with key on before the "hot start"?
As far as I know there is no "high" temp/no start issue in the 4.0l computers
The key on and off 3 times rebuilds lost fuel pressure, but that is usually a symptom of hard Cold Start and loss of pressure over a few hours
Running pressure is 60psi
It should hold pressure above 30psi for many months just sitting
If you have an OBD2 reader have a look at the Computers ECT sensor degrees on cold start and then at hot start
Could be a Flooding issue as well, leaking pressure damper
It is at the end of passenger side fuel rail near the firewall, it has a vacuum hose attached, check that hose for gasoline smell or liquid gasoline
When you shut off the engine if damper was leaking then raw fuel goes into the intake via vacuum hose
Warm/hot engines are easily flooded
So no start on first crank and no fuel pressure
So key on and off builds up the pressure and engine can start
Long shot
