Usually a StarQuest that has issues re-starting 10 to 30 minutes after shutdown is suffering from flooding: a leaking injector (or two) or a leaking fuel pressure regulator lets gas dribble into the intake manifold which floods the engine. Give it enough time to evaporate and the car starts again. Some time when you can drive the car and then park it in your garage/work area do the following:
1: loosen the clamps that hold the over-the-valve-cover pipe (OVCP) to the throttle body inlet and those that hold it to the valve cover. Go for a putt-putt drive (no boost pressure) long enough that you know it'll argue about starting. Park it.
2: quickly remove the OVCP and stuff paper towels in there.
3: unplug the "L" shaped vac hose from the fuel pressure regulator (the small beer-keg shaped thing at the top/front of the throttle body) from the throttle body. Put a paper towel under the end of that hose.
4: Wait a while... then see if either paper towel is wet with gas. If either has ANY gas, you've got fuel leaks.

other then that, if it's a flooding issue, if you WOT and start it, does it start easier?

Sounds like your car gets flooded due to leaking injector or temperature sensor out of range/wiring from that gage (ECU not getting correct info and thinks car is cold (adding to much extra fuel) to the hot engine flooding it. Next time it wont start floor your gas pedal while starting to clear fuel. Hope this makes sense.
