I have a 1989 4.0L 5sp renix that starts just fine but after driving for more than 10 mins then shut it off it will not start again unless I wait about 20 mins or give it some Cosby sauce.

It has a new fuel tank, fuel pump, and new fuel filter. I thought maybe the CPS but it will start and stay running after a squirt of starting fluid. Could this be an issue with the fuel rail getting too hot and it vaporizing the fuel in the lines? Any help would be greatly appreciated.
