That is commonly caused by voltage that's too high. Normal charging system voltage is between 13.75 and 14.75 volts. You can measure that right across the battery terminals while the engine is running. If the voltage is high, suspect the voltage regulator. They can be intermittent too but you should notice head lights getting brighter or flickering.
