ok stopped at a gas station an shut jeep off went in. when i came back out an started it warning beep an no oil preasure . shut it off , restarted an all is good... causes?
The oil pressure sensor could be going bad. I would check all the connections first. You can clean them up and lube them with Dielectric grease. If you end up having the problem again, you could replace the sending unit.
Those issues that happen sparatically are hard to trouble shoot, but you did the right thing shutting it down right away. Let me know if you have any questions!
X2, likely a defective oil pressure sender which is a common issue for TJs. If you decide to replace it, I'd get a Mopar replacement from the dealer and not the local chain auto parts store. It took three different oil pressure senders from Autozone one Sunday when the dealer wasn't open to get one that finally worked correctly on my son's Jeep.

Icarus-I've heard about a drop at the most (if not running, do NOT have it running), just place a rag underneath to catch if necessary. The whole swap took me about 10 minutes overall. The key is to take your time and not wrench on the harness plug when removing.
Get yourself a nice 11 1/16th deep-well socket (at any chain store) and a 1/2" ratchet. The guy at the store I went to suggested I could get it out with a crescent wrench, but I highly suggest the ratchet as you can get a nice, secure grip on it for removal and re-install.
I do not have an A/C unit on my TJ and was able to take care of business from up top, I've heard and read to attempt from underneath otherwise (food for thought).
Again, when in doubt take your time and make sure you do not cross thread the new sensor. Doing this (as with everything else you screw onto your engine block)=bad times
