Hook up a mechanical gauge to the engine and make sure that is the accurate pressure you are getting. You may have sludge buildup on the oil pressure sending unit or valley causing a false reading.

It could also be low idle RPM's, high heat, thin oil and worn bearings.

What kind of mileage on the vehicle?? Like tenspeed said, this could just be a worn engine. If you have worn bearings or oil pump, the symptoms would be the same.
