Car cranks. Turn it off will not crank for an hour what is wrong??

(1999 Buick Century)
I can drive a mile or 10 miles doesn't matter. Once I turn it off it will be an hour or so before it will crank. The engine turns over so it's not the battery. I am wondering during that time is something draining or cooling? I have had a couple of things replaced but has not helped. Mechanic is even stumped. If you want to know what I have had replaced I will have to check. Don't know the names. All I know is the Walmart greeters are tired of me sitting in their parking lot. Please help.

Strongly suspect the crankshaft position sensor is failing after engine warms up! .. Due to sensor location it is pretty tough to get to but it is doable ....... NOW > While the engine will NOT start .. Fuel pressure test along with ignition spark test must be performed to confirm failure.
