1994 Volvo 960 Car won't start after being driven

Engine Mechanical problem
1994 Volvo 960 6 cyl Automatic

I have a 1994 Volvo 960. I can start it, drive it somewhere (short or long distances), shut it off and it won't start back up. I have to wait about an hour or so before it will start again. What could be causing this? How can I check to see what is wrong?

Lets do below for a start to determine if its fuel or spark related issue and get back asap.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/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 packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
