Engine Mechanical problem
2001 Ford Truck V8 Two Wheel Drive Automatic

It is a 2001 Ford Pickup 5.4 motor. The oil pressure has dropped. I changed the oil pressure sending unit and the pressure has still dropped. When I turn the switch off and let it sit overnight, the pressure goes back up when it is cranked the next morning. Then about 15 to 20 minutes later the pressure drops again. What do I do next?

check the pressure with a mechanical oil pressure gauge. if it is low then check the oil pick-up tube, screen and replace if either are damaged/ dirty. if all OK here then suspect faulty oil pump.
