I have the same behavior -- ie. when I leave my computer at night the monitor eventually goes into suspend mode. Then in the morning I come in and touch the keyboard nothing happens. If I log in remotely I can see that X has died and I see the same "fallen off the bus" kernel messages. I put the suggested 'nvidia-smi -pm 1' into /etc/rc.local and verified that the persistent mode is enabled but I still have the same problem. One interesting note for me is that I recently attached a second monitor to my quad-gpu card, and I never had this problem before I added the second monitor. It's possible I had gotten an udpated package at about the same time, but I'm not sure. I'm running up-to-date 13.04.
