The next step would be to pull down, and inspect your ignition switch.(Electrical switch not the tumbler itself.) This switch is located on the steering column itself under the steering wheel.The upper and lower steering wheel cover will have to be removed to check this.The ignition switch(electrical) controls a LOT of the electrical distribution throughout the entire vehicle.This is an easy inspection to perform, and this just might be your concern.If you have a loose pigtail at the switch itself, then it very possibly could be your constant hot lead supply from your batt to your pigtail connector on your switch itself.Do check this out and get back to me.I hope I could help, rate me accordingly, Thanks!!
Your PCM controls the alternator and could be the problem. Get the car started and check the voltage at the battery. It should be steady and above 14 volts. If below 14 volts or jumping around, suspect the PCM or perhaps wiring issue. Especially check the connector at the alternator. Take it off and look at both sides for bent pins or loose terminals. Also look over the cable/fusible link from the alternator to the battery. If it shows any lack of stiffness along it's length, suspect an intermittent open and check with a ohmmeter. If you have questions, please let me know.

I charged the battery enough to get it started and run for a short time. The voltage started at 22 and steadly droped to about 16. It did not jump around just steadly declined. The engine stopped running at 16 volts.
I talked with the mechanic, he does not think it is the alternator or battery, but is not sure what it is.
I charge the battery to the point the car started and was running. The voltage at the battery was 22. It steady dropped over about 5 minutes to 16. At 16 the engine died.
