IMHO, yes. I had exactly the same symptoms with my PowerBook 12". It'd run fine for a while then not restart. Leave for a couple of hours, it'd restart. Did this a couple of times then was fine for a couple of weeks. I made sure that the nightly backup was running OK and then, after a heavy days work. Boom. Left for a couple of hours, still wouldn't restart. Happily, after a rest overnight, it rebooted. I did a full backup and sent the machine off for repair as I realised that loosing even a days work could be a real bummer if it was the wrong days work. FYI, I used to boot the machine in target disk mode a lot and use it as my home directory on a desktop machine. Now I have a little LaCie portable firewire drive which does the same task - it Velcros to the back of my PowerBook when I need to travel. And yes, the LaCie drive is backed up every night at 10:00 pm, assuming it's plugged into the desktop machine.
