1997 delta 88 starts up just fine but after running a few errands wont start up. Let it sit for 20 minutes, then starts right back up. What's wrong with my car.

you should have your car scanned to see what is happening. Is the control module getting hot and stopped sending the signal for spark? Is the crank sensor sot sending the crank signal to the pcm? Is the coolant sensor open so the computer is flooding a warm engine? Is the security light flashing? Cycle the key from off to run without starting the engine. Can you hear the fuel pump run for the two second prime and then hear a click and pump turn off? (it's going to be a very light hum sound when the pump runs)

So many things could cause this. with a scanner hooked up and run until it won't start you should be able to look at the data stream and see what is different for the no start.

Not always, but it's a first step. Crank signal. Coolant temp. signal, injector pulse, mass air flow, security, fuel pressure...
