94 Exp. Hot engine start problem

[OldManVic]

A 94 Exporer XLT 2WD 6Cyl.

When the weather turns HOT I can start the car the first time that day with no problem. After driving a couple of miles and stopping, the car will crank over, but it will not catch. If I let it rest for anywhere between 5 minutes to an hour, depending how the Ford Gods feel that day, it will start up and I'm on my way. Cold to mildly warm days pose no problems...Just hot.
Any helpful ideas will be appreciated.
Thanks!

Do you hear the fuel pump prime when you turn the key before you crank the starter?

Yes, I do hear it.
