Sounds to me like your hard drive is dying. You should back-up your data the next time your succeed in booting and then replace the drive.

Foe easy restoration, use Time Machine to backup to your external backup drive.

Yep sounds like the hard drive. Once you start it up again, use disk utility to try and verify the disk, then repair it. ...but still be prepared to change it as they never last forever. Mine did the same last week by the way and I am in the process of installing a new one.
