Here's a possibility, related to heat.  That third pin on the ignition module is actuated by a thermal switch somewhere, I think.  So it might actually be the ignition module.  I think that you can test that by short-circuiting the switch or the module.  You could explore that by examining the FSM chapter to see how, exactly, it works, in the meantime.

New module arrived yesterday. Installed...and then started up car. No more problem. I let it run for about fifteen minutes to make sure, and then drove it to the car wash. Afterward, I took it on a twenty-mile cruise. Except for an occasional miss at higher revolutions, everything was great. I think the miss is caused by the very old gasoline that was in the tank. Car was started every week for four years, but nowhere near a gas station. Former owner lived in the country. After I dropped $30 worth of Chevron Supreme into it, it smoothed out quite a bit. I also figured out the shocks are pretty damn old and need replacing. Other than that, no problems. 

I would also like to thank the people who came on this thread to help me. 

Excellent!

I purchased a back up module and keep it in my Z's glove box. Just in case, you know? I also tested it when I received it, thats how I discovered the first one was bad. Too many defective ones on the market for purchase so beware. And price differences.
