The inductor used in the previous motors was under rated for current such that repeated stall current would eventually burn open the inductor. This does not sound like RF interference as that would produce more problems and generally be not repeatable. RF is at it's highest while the motor is running wide open or under heavy load.

I would agree except that it would do it when the motors were unloaded, i.e the robot was up on blocks just spinning it's wheels. What is completely puzzling to me is that this is a pretty standard FTC configuration.
But I would also agree that my explanation, (RF issues) is unlikely.
Not knowing the root cause puts our "fix" in the realm of voodoo and that is particularly unsatisfying.
