You need to try to validate it with a guage other than the one in the dash. The sender could be failed. If the motor doesn't make any noises when it shows no oil pressure, there is a good chance it does still have pressure, but that the sender failed.

What do you have for pressure while you are driving?

There is a pressure regulator in the rear oil cooler header inside against the block.
It is not servicable.
The rear oil cooler header lists for over 300 dollars at Ford.
