Screen goes black randomly?
So my MBA is going on about year old this March-
On occasion while working, the screen will just go black. I then press the power key and it comes right back to life.

Caffeine will temporarily override your energy saver settings and keep your Mac awake with a click on the Menu Bar icon. Another click turns it off.
Also make sure you don't have a hot corner set to sleep the display.

Does your case, bag, or anything you keep around the Mac have a magnet? Sleep is initiated by a magnet in the lid, so other magnets will mess with it too.
Do not fark with your Mac if you don't know what you are doing.

Probably a longshot, but I use the "hot corner" settings, where the screen turns off when moving the mouse pointer to a specific corner (to save battery if I know I won't need the screen for a few minutes). A friend borrowed it for a while, and he came back complaining that it randomly shut down the screen :P Maybe worth a check that it wasn't activated by accident. You change it it System Preferences -> Desktop & Screen Saver -> Screen Saver tab -> Hot Corners.
