How close is the sensor to the magnets? If the gap is large the sensor will get less of a signal from the magnets and it might be that at speed (when
the magnets are moving quickly) its too quick to trigger the circuit. Worth a shot anyway

Yep, I had a similar problem and 'fine tuned' the gap down to not much at all. Working well now though.
