It sounds like a bad wire or connector between the TP sensor and the ford computer.

First thing to do is to allow the engine to idle and start wiggling the wires at the TP sensor first slowly up and down and around and listen for any changes in rpm from the engine or any clicking sounds. Continue to do this working down from the tp sensor all the way back to the ford computer. Pay particular attention around the top of the transmission area. I've seen many times where the wire harness will rub against the trans pan area. Move the wiring around to be able to see all areas of the wires for any signs of wear or exposed wires. It works best to move the wires slowly.

Also remove the connector at the tp sensor and see if the pins are pushing out or spread apart.

It almost certainly has to be a wiring issue. TP's from ford don't fail that much.

Of course if you find anything in the wiring repair as needed.

Let me know what you find. Come back to this same post for more help if needed.
