CRANKSHAFT POSITION SENSOR LOCATION FOR 4.0L ENGINE IS ON TRANSMISSION BELLHOUSING AT THE LEFT REAR OF THE ENGINE. FOR 5.2L ENGINE CRANKSHAFT SENSOR LOCATED ENGINE BLOCK BEHIND THE RIGHT CYLINDER HEAD.

4.7L ENGINE CRANKSHAFT SENSOR LOCATED ON THE ENGINE BLOCK ABOVE THE STARTER. ON THE 4.0L ENGINE CRANKSHAFT SENSOR LOCATED TRANSMISSION BELL HOUSING AT THE LEFT REAR OF THE ENGINE. THE 5.2L 5.9L CRANKSHAFT SENSOR LOCATED ON THE ENGINE BLOCK BEHIND THE RIGHT CYLINDER HEAD.

1st I need to know what engine you have, 4.0L or 5.2L V8.

Its not unusual for the crankshaft sensor to intermittanly fail. The crank sensors are not real expensive and are not extremely hard to change.
The Crankshaft Position Sensor (CKP) is mounted into the engine block above the starter motor. Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the powertrain control module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along with other inputs, to determine injector sequence and ignition timing. The sensor is a Hall effect device combined with an internal magnet. It is also sensitive to steel within a certain distance from it.
Below is a pic of the sensor location.
Good luck.
Regards,

Check spark to plugs. Possible crankshaft position sensor. Located at rear of engine between engine and trans.
