Have this checked out: The Electronic Voltage Regulator (EVR) is not a separate component. It is actually a voltage regulating circuit located within the Powertrain Control Module (PCM). The EVR is not serviced separately. If replacement is necessary, the PCM must be replaced.

You have an intermittent problem so the testing has to be done while the problem is occurring. Brushes in the alternator are the most common source of trouble, and can be replaced separately for 9 bucks, but I would never do that without performing some tests first. When the problem is occurring, measure the resistance between the two smaller wires on the back of the alternator. If you find an open circuit, the brushes are worn.
