The motor cables contain wires for both power to the motors and reading back the encoder signal from the motor to see how fast the motor is turning.
Sounds to me like the latter signal is not getting through, ie a broken wire in the cable or a bad solder joint.
For what its worth, a broken wire in the cable may also explain why the mount seems to stall at a certain point, maybe the cable is being bent just right to go open circuit.
You could check this by swapping the RA and DEC cables and see if the problem moves with it, or flexing the RA cable and see if you can provoke the problem.
