problem #1

This problem was brought to the attention of the dealer. They ran a diagnostics to try and find the problem. Told me that the car had problems that needed to be addressed. The fuel pump and sending unit needed to be replaced. One ignition coil was bad. Cost $1250. I changed the parts myself - problem still exists. Can anyone give me a clue? Is it the alternator overheating? What is common to the window motors, the rear window defroster and the door lock? HELP!!!
Once the car dies, it will not start for another 1 -2 hours. Then it is like it never happened. Starts right up. Drive it a little bit, roll down a window and die! Why is this so?
