Could be a defective or faulty battery. There are several things you should do though first to help try and improve the iPod's overall battery health. The first is to turn off Wi-Fi whenever you don't need it or can't use it. Instead enable Airplane mode from within Settings.
Another good idea to be to close Apps that in your multitasking tray/bar when you are finished with them. To do this, double click the Home button. Tap one of the listed apps until a small red sign appears over the upper right hand corner of each. Tap this icon to remove the app from the list.
