Perhaps you could connect a DMM and watch for any voltage excursions. If the voltage drops at the time I would assume that the alternator is working hard.
What could create electrical loads? The rad fan, but I can't see why that would come on when at speed as the vehicle air flow is often more than adequate for cooling. Could something be abnormal about the cooling system?
Battery cell shorting out intermittantly? Battery old?
