I think you're probably a victim of the junction in the driver's door accordian. There is a connector there that get's corroded or the pins get deformed and causes exactly the symptoms you're describing. Open the door, pull back the accordian and you can see the connector. There are actually two connector there. Disconnect both of them and remove the accordian so you have some room to work. Look carefully at both the male and female components. You may find one or more deformed and not making a good connection. Using a small scribe, fix the female side and make sure everything is clean and dry. Reconnect everything and there's a good chance the problem is solved. This is a fairly common problem.
Also check all the grounds in the engine compartment and also the injector harness that runs behind the driver's side head to make sure that's not abraided and shorting out.
Don't ask me how I know....

That being said, Kevin's advice is solid in inspecting the door wiring. Since the engine has been out of the car, I would be more concerned that the grounds are secure(as opposed to clean)....starting with G106.

If you check your codes you'll find lots of U codes caused by the power fluctuation. Clear them down and you can check if your fix has worked.
