Question about 2002 Ford Ranger Regular Cab
If you have checked the oil level and know it is full and not overfull, then you need to stop driving the truck until you solve this problem. It can be nothing more than a loose wire on the oil pressure sending unit. Or the sending unit can be bad. The gauge can also be bad. But is can also be a weak oil pump, or clogged oil pick-up screen. Considering it does this after it reaches normal operating temperature this is very suspicious and sounds like possibly engine wear. An oil pressure test and compression test will help diagnose the cause. You can just go ahead and check the wiring at the oil pressure sending unit and replace it if the wiring is good to eliminate that as a cause. If it is leaking it is for sure bad.
