Failed Oil Pump on 1996 Chevrolet Lumina

The car stalled while driving. Repair shop says there's no oil pressure so oil pump must have failed and needs replacing. $750. Q: How common is oil pump failure and can it be clogged oil galleries? The oil is very dirty, I don't know when my son last changed it.
