When I start my car in the morning, the oil pressure is fine. After I drive for about an hour, the pressure drops to below half on the gauge. Lately the pressure is dropping to zero when I come to a complete stop. Do I need a new oil pump?

Could be worn engine parts, too much clearance between bearing inserts and crank. Try using a heavier oil blend, say 20-50 or straight 30 non detergent.
