Hi there, sorry to hear you're having trouble,
do you have any issues with the tuner (am/fm radio) mode?
If you only have the problem with the cd/tape, that could just indicate contamination, meaning the tape heads and laser lens are skipping and need to be cleaned. If it happens in tuner mode too, that would indicate an internal hardware problem, either the amp is cutting out, or there is a processing failure in the main/control board.
