It never fails in the morning. From that, I concluded that it might be heat related and/or have something to do with not locking the car, while parked in the garage. When it starts and runs, it runs normally. It never stalls. I have replaced the following: 1. Fuel Pump, 2. Fuel Filter, 3. The Fuel Injector Regulator, 4. ECC (PCM) Power Relay, 5. The Fuel Pump Relay, and 6. The Ignition Switch. I even bypassed all electrical components controlling the Fuel Pump. I did it with a push button switch. When it fails, I press the push button switch and can hear the Fuel Pump run. But it still does not start. From that, I concluded that it is not a Fuel Delivery problem. If I leave the car sit long enough, it will eventually start. It's driving me crazy. Can anyone help?

Check the Ignition Coil.I have had problems similar and found that when the coil got hot, the engine would not start after running moments earlier.

Your problem is best solved by using the professional car technician forum http://www.IATN.net However, access to their data base of similar problems requires paying a subscription fee. It might be worth it in your case.
