Mouse Freezing…Power Supply Issue?

My mouse randomly freezes for short instants of time, then works again. It worked great for the longest time, and now this. I use a corded Logitech Optical Wheel mouse through a USB port in WinXP. When it happens, the cursor freezes, the red light from underneath the mouse stops, and windows makes the usual “a USB device has been unplugged/plugged-in” sounds. The actual freeze length depends… goes from 5-15 seconds. Any suggestions?
