Do you hear one loud clunk from the starter? Is so, you have worn solenoid contacts. Keep cycling the ignition switch; it will crank eventually. This problem will get progressively worse over time. New contacts are 20 bucks, but most people just replace the entire starter.
If you do not hear that loud clunk, or the starter relay either, suspect a broken metal cam on the end of the ignition switch cylinder. Everything will work except the starter because in effect, the switch isn't turning quite far enough. This usually isn't intermittent in nature, but it sounds like something to not overlook. The dealer has an inexpensive repair kit for this problem.
