 If the starter motor itself quits rotating, rather than rotating but no longer turning the engine, then the problem might be a worn-out or oil-soaked contact brush.  Replacement brushes are sometimes available, but require spot-welding to install (the local starter repair shop ought to have the equipment to do this).  As an alternative you could replace the starter with one of those high-torque geared starter motors.

If the starter motor continues to rotate but won't turn the engine, you probably have a problem with the starter's bendix gear, or perhaps a loose ring gear on the flywheel.  In the former case, I'd suggest replacing the starter as above.  In the latter case, you could pull the starter and see if  it's possible to tack-weld the ring gear to the flywheel; if not, you'd have to drop the transmission and pull the flywheel for an on-the-bench repair.
