I re-seated all connectors, SATA and Power. If it happens again I have another power supply I can try.
I researched a few other possible issues. The SATA Crucial M500 has an old firmware MU02 latest is MU05, and some of the release notes mention Haswell platform problems. I also found the logs in Event Viewer at the exact moment the drives disconnected. Here is some of it.

What I take from these is IDE port 0, or maybe SATA Port 0? I have either the Bluray burner or the Samsung 850 128GB SSD on that port.
Just thought I would share this new information. Anything can help.
