Today, after I had driven our 99 cherokee for about 6 miles in the first 95+ degree weather we've had here in San Diego, when I pulled into a parking spot, I noticed the oil pressure dropping rapidly, and basically sat on "0". With the "check gauges" light and chime coming on. Recent oil change, checked the oil it's full, but when idling or at very low speeds the pressure drops way down. Once going, it goes back up towards 50 where it should be.

Clogged filter in the sending unit, oil pump, or anything else it could be?

I'm stumped.
