I vote for the starter, especially if you hear one loud clunk from the starter when it doesn't crank. Worn solenoid contacts are real common. They can be replaced, but most people just replace the entire starter. Just keep cycling the ignition switch. It will crank eventually but it will get progressively worse.
Rasmataz hit all the possibilities, but you'll have to provide more clues, observations, or voltage measurements for him to narow down the problem.
