OK.I can crank this Jeep up, with giving it some gas. Then it will stay on and idle at like 500 rpms for about 30 seconds then it dies! What's wrong?

You need to check fuel pressure before starting and while running, so you will need to find a pressure test guage and connect it to the schrader valve on the fuel rail.. If that tests good, you may be having a problem with your Crankshaft position sensor, Throttle position sensor, or a few other things.
IAC, Camshaft sensor. Bad ground connection.
If no check engine light. Probably Cranshaft sensor.
If you are handy, and have the tools, get a Service manual start with a fuel pressure check.
