I'd suggest the ignition control module, however I'd have a certified mechanic check it out just in case...

There is a vacuum leak under the hood. If it's a 6 cylinder, look on the drivers side for a vacuum line that runs vertical with a 90 degree angle fitting to the manifold. That one usually comes off. If it is a V8 look on the battery side for a broken or corroded vacuum line.

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.
