Washer is 15 year old top loading model.

I had this happen on a much older Kenmore/Whirlpool belt drive washer. It
turned out to be a slightly misadjusted clutch. There were two hex nuts on a
threaded shaft, locked against each other. Loosening them and making a small
adjustment of there position on the shaft caused the spin cycle to resume
normal behavior.
