I feel bad about your experience. I am an analog diehard for over 20 years and have owned a few turntables. However, I have never had any experience remotely related to yours. All the tables I owned and the one I still own never stops during music playback. I don't think voltage fluctuation will stop the table. It may affect the spinning speed. All my tables are plugged to the wall directly and never see any power treatment.
Since it is still under warranty, I would send it back for repair or exchange if I were you. The time you spend monitoring it or diagnosing the problem should be spent on listening to music. Hope you find a solution very soon.
