I lost oil pressure

two things, did you look at the oil pressure sensor to see if it is leaking oil out the plug end, and is the engine making any "new" noises....like a valve tap? It is common for the oil pressure sensor to fail, most times it is accompanied be an external oil leak from the sensor.
If it is not leaking you would have to test the oil pressure to verify that the oil pump is working correctly and replace the sensor if it is.

Almost assuredly the oil pressure sending unit. They are a very common fail.
You could verify it if you want by temporarily installing a "mechanical" oil pressure gauge where the oil pressure sending unit resides. Or you could just buy a new sending unit. Do yourself a favor and buy it directly from Jeep for the best reliability and longevity.
Good luck!
