Question about Cars & Trucks
Must be some bad information getting to the ecu. Bad conections due to salt corrosion may be the cause. Bright metal contacts are essential for correct transmission of information from sensors to and from the ECU (brain).

Guages are put on vehicals for a reason not just for looks i would have the car hooked to a diagnostic center and checked even though the guage may be faulty but i wouldnt take a chance

Have the oil pressure tested with an accurate mechanical gauge. often the sending unit goes bad, but without testing it could cost you an engine before you find the problem.
If the mechanical gauge shows same low readings, you have internal engine wear (likely worn crank/rod bearings) Then, it's your decision on whether to drive it till it expires, repair it or buy a new vehicle.

You need to replace the oil pressure sending unit, this is what tells your gauge what the pressure is. For future information if your oil pressure drops again and its a real failed oil pump within a few minutes you will internally damage the engine. I would get a new Oil Pressure Sending Unit. Let me know if you have any questions.... Thanks!

There may be a loose wire or the gauge or sending unit may be going bad. The first thing I would do is to hook up a temporary oil pressure gauge, not using the old one at all. With this watch gauge while driving and see what readings you get. If the readings still jump around you have a pump that is getting weak and failing, If that is the case the pump should be replaced, but with high milage you may consider rebuilding the entire engine. If the readings stay normal start checking for a loose wire at gauge or sender. Then check sender, then gauge and replace as needed.
