Thank you for the memory check, and verifying it is not linked to SD card.
You could check or attach /var/log/kern.log.0 file too.
If you have an other computer to connect to it (or from it), you could try one of the following: -Remote Debugging in https://help.ubuntu.com/community/DebuggingSystemCrash -https://wiki.ubuntu.com/KernelTeam/Netconsole (which could be a bit too technical however).
