You need to list the engine size when asking about an engine running problem. In this case, I'm guessing you have a 4.0L. Start by checking the diagnostic fault codes. Cycle the ignition switch from "off" to "run" three times within five seconds, leave it in "run", then watch the code numbers show up in the odometer display. Holler back with those numbers.
