My car has never done this before. I was driving, like 50MPH, when all of a sudden, everything quits. Engine stops, no power, no nothing. I was able to steer in a parking lot. 
I had absolutely no power whatsoever. No GEN light, no starter, no radio. Completely dead. I waited about 15 minutes, ready to call a tow, I tried it and it started right away like if nothing had happened. 
I drove for another 20 min, and blawwww. Same thing. Waited 5 minutes this time, and started right away again. It did this all afternoon!!! Randomly 
I had the hot-start problem with the Firebird. After a while, it wouldn't start because the starter was too hot. But at least, I had power!
Battery seems to be fine, lots of cranking power.
What could that be? Ground problem? Ignition switch? Alternator? I'm lost. And desperate.
Thanks

If it were me, I would do this first.....
Look at your positive battery cable and follow it all the way from the batt to the starter looking for chafing. Do the same with the smaller gauge engine harness wire that attaches to the starter, and the large diameter wire that connects to the main termin al on the back of the alternator......look for loose connections and chafing of the wire insulation
If nothing there, then look very closely at both of the bulkhead connectors where they attach to the fusepanel.....maybe the engine harness connector is loose with one or both clips broken....
