Did it stop registering oil pressure recently?
No oil pressure showing on the gauge at all RPM?
Is the engine making bad sounds?
Do you have the valve cover off to see if oil is getting to the rocker arms?
Oil pumps don't go bad very often. Pick up screens do get plugged with sludge however, and gauges can go bad (not often though).
Need a lot more information to help you pinpoint your problem.
