Test the oil pressure switch. These go bad and it has nothing to do with loss of pressure anywhere else on engine.

Guys, My 2011 xlt was doing the same thing. Manually tested the pressure and it was good so knew it had to be the switch. At ford there’s 2 versions of this switch, make sure you grab the most updated one and that should fix the problem. My mechanic ordered 2 A parts and it didn’t work but ordered part b and finally worked.
