Ah, missed this bit. So it is not happening to every motor. The first couple of times you ran the 1515 did it get excessively hot? Is it possible you demagged the rotor just a little, so the cogging happens at the higher temp range? Particularly in the middle or at the end of a run when there is less voltage to feed the system.
The 1515 would be more efficient as it is a longer motor which would explain some of the runtime difference, but I don't know if that is the complete story. Do you drive differently with the two motors? eg- light on the finger for the 1515 because of more torque.
