It actually could be several things:

1.Starter Solenoid.
a) Have you heard any godawful grinding noises upon startup lately?

2.Crank Position Sensor
a) Has the car lately cranked without actually turning over?

3. Ignition Relay

4. Could be very low voltage from the battery causing any one of these problems


Any CEL on in the car?
