1982 Buick Skylark 4 cyl Two Wheel Drive Automatic 150K+ miles

After the car warms up, it will not start after sitting for 10-15 minutes. It starts fine immediately after turning off, but won't after it sits. I haven't had the opportunity to look in the carburator or check for voltage at the spark plugs when this happens. It cranks, just won't fire. Any ideas?

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-
