iPod keeps rebooting

I have a 10GB 2nd generation iPod, and after a good 3 years of constant use, one day it started to reboot in loop, never making it past the Apple logo. After a few hours of searching, I was able to locate the proper diagnostic keys to fix the issue:

1st, 2nd, and 3rd Generations
Reboot iPod: Hold down the menu and play buttons.
Disk Mode: Hold down the rewind and fast forward buttons after a reboot.
Diagnostic Mode: Hold Rewind, Fast Forward, and Select buttons after a reboot.

Mini, 4th, and Photo Generations
Reboot iPod: Hold down the menu and select buttons.
Disk Mode: Hold down the select and play buttons after a reboot.
Diagnostic Mode: Hold Rewind and Select buttons after a reboot.

After I got it into Diagnostic mode, I put it into 'USB Disk' mode in hopes that I could run the Apple iPod Updater software and restore it. After a few attempts, the Updater would run, and then give the error message "Can't unmount iPod". This was due to the fact that the 2nd generation of iPod's were not powered by USB. The solution? I had to connect the iPod via FireWire to my system, set it into Disk Mode and then run the Updater. After this, the Updater worked correctly and I was able to fix the rebooting loop.
