After it shuts off it cranks but won't turn on till 45 minutes to 1 hour later it starts. took cover off does has pray pattern when I crank. Replace spark plugs the wires ignition coil. Took it to shop this week they said it was the distributor They installed the distributor I took it home ran in drive way for 30 minutes shut off again waited 1 hour later turned on. Please I need help Mechanic charged me 800 to put distributor in. I just won't it fix so I can enjoy it.

Do you ever get a CEL light? If so, what is the code set? $800 for a dizzy change is ridiculous. 
You could have put a DUI dizzy in there for under $325 and be much better than a stock one. Why did they say the dizzy was bad? I would have went for a module change first which again is MUCH cheaper. That shop ripped you off.

Do you have an 84 GM service manual? If not, get one. It has all the troubleshooting in the manual you should need to find the issue. If the dizzy was replaced as an entire unit, the module would have been replaced as well. So, it appears that a heating issue is not the cause of a module failure. Next like mentioned would be to check the fuel pressure and set it to 13psi and be done. GL
