This exact same thing started happening to me when I started working on a bus. The bumps on the bus seemed to put my macbook to sleep. Now I'm back in the office, if I jostle my macbook a certain way, it falls asleep, then I tilt it back and forth, and it wakes up. I'm guessing it must be some kind of accelerometer bug... please help if you figure it out.
