While driving down the road the car would just cut off after sitting for a while it would start up

You mentioned the fuel pressure was good, was the fuel pressure checked while the car will not start?

Don't know that's what the two shops told me can her the fuel pump come on when the switch is on

Can you ask them come Monday. We need to know if the concern is in fact no fuel pressure to blame.

Hi, Chris talk to the guy that worked on it. He said,with the car running or will not start it was getting fuel to the motor. Also said when the car would not start known of the sensor would work. When started all the sensor would work.

If none of the sensors are working, this means there getting no 5 volt reference voltage which comes from the PCM. This would mean the PCM is faulty.
