2000 Jeep Grand Cherokee Drove Car Store Engine Light Came On Coming Out Store

Don't just change a fuse. Look at it to see if it is actually blown. I doubt it is because the engine would have stalled while you were driving. The next time it won't start the first thing is to listen for the hum of the fuel pump for one second after turning on the ignition switch, then check for spark. If you get the hum but no spark the automatic shutdown (ASD) relay isn't turning on during cranking. That involves the crankshaft position sensor and the camshaft position sensor. Since the Check Engine light turned on there will be a diagnostic fault code stored in the Engine Computer. That code will indicate the circuit or system that needs further diagnosis.
