The period between the spastic episode is what caused me to suspect that direction...

You hit it restamp, the space saver tire and the different rotational speeds on the inside and outside tires in a turn are fine. What the system is looking for is a skid (no rotation at all) which can be caused by a bad sensor, bad wiring, loose connection, bad plug on the ECU connection or a bad ECU (the most common issues).
