I suggest taking a look at the Crankshaft Position Sensor. Is the service engine light on? If so, you should get the codes pulled and see what it says.

There is a crank angle sensor inside the distributor.
That would usually set a code 41 though if it were bad.
Here is a test,
CODE 41 - CRANK ANGLE SENSOR SIGNAL > DIAGNOSTIC AID
Disconnect crank angle sensor harnesses at crank angle sensor connector.
Disconnect all connectors at ECM.
Turn ignition "on". Measure resistance between terminals 34 and white, 35 and green and black and ground. Resistance should be zero.
Measure voltage between green/black and ground. Voltage should be 10-14 volts.
When circuit is found to be in normal condition, replace distributor assembly.
