From a trusted tech:

I've never heard of a run capacitor in an 8-Track. 8-Track players use DC
motors with permanent magnets, and "run" capacitors are normally used on an
AC synchronous motor. It's more likely that the motor's bearing is shot,
which would cause that same symptom. Other causes are also possible.

Yes, I tried it again today, and it works fine for the first minute, then
slips into 'underwater mode'... snip

Replace the motor run capacitor...done.
