Bug Description
This happens on Ubuntu-Gnome 14.04.X(X being initial release and all point released after) through 15.10. The OS itself is fine and can be booted into again by reinstalling Grub but will eventually happen again.
This bug can happen right after a new install of Ubuntu-Gnome or many months after. When it does happen, the system works and acts the same as before and after the bug.

Grub shouldnt just disappear!
Does running "update-grub" break it? (that would get triggered from time to time on system updates)
You dual boot with Windows? Is it possible that Windows is messing with the UEFI Boot Manager? Or does it happen when you reboot from Ubuntu?
I notice this diffing your before and after logs: platform_ search_ hint = xy ]; then bios=hd1, gpt2 --hint-efi=hd1,gpt2 --hint- baremetal= ahci1,gpt2 5290bec0- f256-4adf- 804a-c44597538b 95 bios=hd0, gpt2 --hint-efi=hd0,gpt2 --hint- baremetal= ahci0,gpt2 5290bec0- f256-4adf- 804a-c44597538b 95

if [ x$feature_

+ search --no-floppy --fs-uuid --set=root --hint-
I don't know why those would change, perhaps grub got confused and used sdb to configure instead of your ubuntu partition (sda)
