Sounds to me like a 'flying short' in your alternator. Not all that uncommon. Best bet would be to try a known good alternator first. Sometimes the centrifugal force of high rpms will cause an open or short in the alt. windings then all you are reading on your guage is battery voltage because the alternator has stopped charging. It may only happen when hot because it's just starting to fail and thermal expansion is contributing to the failure.
