Howdy Red9654,
From what you describe I believe this to be a software issue. In light of that, I recommend a few troubleshooting steps.
First restart the iPod and test again. If the issue persists then reset the iPod.
- Press and hold the Sleep/Wake button for a few seconds until the red "slide to power off" slider appears, and then slide the slider.
- Press and hold the Sleep/Wake button until the Apple logo appears.
Note: Reset your device only if you are unable to restart it.
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.

If that does not resolve the issue I would recommend restoring the iPod with iTunes.
