I had his issue, with mine we didn't drive the truck much and it developed an oil sludge problem. The sludge was in the oil pan and while the truck was under load, the sludge would temp. block the oil pick up which would cause low oil pressure, then cause the engine check light. We dropped the oil pan and cleaned the pan, screen and pick up tube, also changed oil. Been running good after that.
