oil pressure switch fixed my problem. My oil pressure gauge would drop on cold mornings and yesterday it dropped and stayed at low for 2 or 3 miles and the engine shut off and would not restart.I had it towed home and after reading this forum i decided to replace the oil pressure switch and change the oil,truck is running great now.

The problem is the oil pressure switch. Sometimes more commonly referred to as the oil pressure sending unit. On these trucks, the switch is an "All or nothing" sensor. The gauge on your dash does not actually show true oil pressure. It only tells you if you have any oil pressure or not. The switch/sending unit/sensor (whatever you want to call it) it located just under where your oil filter screws onto the block. The one on my 5.4L 2001 Expedition took a 3/4" wrench and some swearing to get to it because it's tight in there....but it basically looks like a spark plug screwed in there with a small, 2 wire, wiring harness connected to the back. You will need to remove the oil filter to get to it, so plan on an oil change at the same time. I just replaced mine yesterday after a few months of sporadically showing no oil pressure. I picked up the new sensor at O'Reilly's for 6 bucks.

The oil light on our 1994 Ram truck was going up and down and then just stayed on. The outside temperature Is about 10 below zero.

Any suggestions?

Thanks for the help!!

My 2000 Expedition has started doing this since Jan as well. I am going to replace the oil pressure switch and see if it fixes the problem. Does anyone know where the switch is located on the 4.6L? I can't find any mention of it in my repair manuals.
Just had oil pressure sensor replaced and it's doing the same thing. So maybe oil pump?
