Truck loses oil pressure while driving. Replaced the sending unit, new oil and filter. It was fine for a day and half. Was driving and lost pressure again.I pulled over when the gauge dropped, turned it off. Didn't hear any strange noises.Waited 5 min, started it, and it was fine. The gas gauge was screwed up a few months ago, but it works fine now. Could it be electrical? Oil pump?
It would start at 40, then steadily drop to 0
