Oil pressure gauge goes to zero

    I loaded up the wife and kids today to go out to lunch and as I got to the bottom of the driveway I saw the check gauges light on. The darn oil pressure gauge was at zero. I just changed the oil a few days ago so I thought Oh crap I didn't put the drain plug or oil filter in tight enough. So I checked the dipstick and the level was fine. I thought it may just be the gauge so I started up the car again and the needle went right to where it should have. It did jump around a little within the ok range. After a minute it worked perfectly. So, is some sensor not working, is there a wire loose, computer on the fritz?

    BTW this is my wifes 2000 Explorer w/ 4.0 SOHC. I come to ya'll to diagnose the Ford problems because I know it gives you great joy.

    I'm the proud owner of a 2003 Silverado 2500HD.
