Lets give this a try: Do you have an external drive (FireWire being best here). Using the Mavericks installer prep the HD and make it bootable (a fresh disk would be ideal). Once you get to that point alter the boot disk setting so this fresh system is not used for the boot up. But run your apps from the internal HD. Set the system up to the expected failure point and see if the problem still happens. If it clears it up we know something you carried over from your restore is messing things up. If the problem is still present we'll need to dig into this deeper.
