Okay, then you are losing spark or fuel to the engine. You need to check to see which one is missing and let me know which it is. Then I can help you from that point.

Let me know what you find.

If this turns over but won't start you need to let us know.
On these older vehicles the coil plug sometimes broke off from the dist cap andmade vehicles hard to start. If it won't turn over, make sure that the battery is grounded to the engine and from engine to frame and engine to body. You may be not starting from a por ground and when you go to hot soak it makes it difficlut to turn over. It may also be teh solenoid not allowing power through it or the starter may be drawing to many amps. This can be checked at an auto parts stores.
