Default [Q] Bricked Galaxy Nexus ?

Hi
I hope that my GN isnt just brick right now.. So to the main problem. Ive got the restarting problem. About 3 months ago my phone was restarting once in week, I thought its normal,but about one week ago, I turned my phone and it holded for 1 minute and phone restarted itself. After all, I tried a factory reset but it didnt work, Ive got into recovery mode with android and redcross above it. I tried a push another recovery through Fastboot, but everything were fine, till I restared phone and everything was the same...No new recovery.. The main problem is Ive got unlocked Bootloader, when I tried to lock it through Fastboot, it told me "bootloader locked" but after reset the bootloader was unlocked again...
Can anyone help me please ?

Happy owner of the Galaxy Nexus..
