What year is your Jeep ? XJ Cherokee, or a WJ Grand Cherokee ?
Specifically what idiot light comes on, the Check Gauges ?
Describe "nothing", what do you do, what does the Jeep do, what do you hear and see when this "nothing" thing is happening ? Does the fuel pump hum for a few seconds when you turn the key ?
From your limited description of the problem, you should have the battery and alternator tested. Make sure all the wire connections to the battery, alternator, and starter are clean and firmly attached.
