You don't have a Fusion disk in that machine, I hope?

Supposing it's an SSD and not Fusion or spinning rust, it's starting to feel as if something's wrong with the SSD. I sometimes see this kind of stall with the older MB Pro's that have a slowly failing SATA cable. It's not regular, tho. These cases are very irregular and finally result in complete lockups.

Got an external disk to boot from? That would be the easiest way to test.
