The battery is on the way out. Unless you want to get the battery replaced you will have to go get a new iPod. The same thing has been happening with mine for about 3 months. And mine will be 3 years old this Christmas. I only use it when it is connected to a power supply, which is good for me anyway, because I have an FM Transmitter that charges the iPod. So, I suggest you get a new battery, or wait until September for the new iPod's come out, which is what I am doing.
PS - Don't appreciate you using the word 'gay' as a derogatory term.
