It is likely you activated a security routine by doing something. Itunes has the ability to kill your ipod.
Try doing an alternate restore procedure. While the device is off, press and hold the home button, and simultaneously plug the iPod Touch to your computer. Try to read this article. http://factoidz.com/how-to-fix-common-issues-for-the-iphone-and-ipod-touch/ The procedure is actually for a frozen iPod Touch (device stays forever on apple screen), but being that you haven't tried it out, and since it's a standard restore procedure, maybe you could give it a try.
