F150 LOSING OIL PRESSURE

2000 Ford 500 • V8 4WD Automatic • 114,000 miles

Hi I have a 2000 ford f150 supercab 4x4 with a 4.6litre triton (romeo) motor. When it warms up I completely loses oil pressure. Now I can shut it off and then start it right back up and I will have oil pressure again for about 30 secs to a min. I changed the oil filter from a motorcraft to a stp and put 10w-40 motor oil in it and it still does the same thing.

I also ran a gauge test and the oil pressure does go clear out

And it does not change if I rev the motor or not.

So you are saying with a mechanical gauge installed, pressure drops to "0" (ZERO?). Does not come back up?

If this is the case, are you experiencing Engine Rattle/ Clatter/ or Knocking?
