Symptom
Engine light comes on when rpms increase and shut off at idle. Help from people on this forum indicated that this was a classic symptom of a voltage regulator (VR) failure.
Testing
Using a multimeter I was able to verify that it was indeed a VR failure. At idle the voltage across the battery terminals was 14v and at 4000rpm it climbed to almost 19v. Since it should never go over 14.6v this indicates VR failure. Running a PTW in this state would quickly ruin the battery.

Procedure
1. VR is located here.
2. Remove the rear most piece of plastic directly under the trunk lid by removing the 4 screws indicated by the red arrows.
3. Remove the right rear tail light assembly by taking out the rear screw, sliding the unit out and unplugging the wire connector.
4. With the tail light assembly removed you can see the VR. Remove the two screw indicated by the red arrows on the front and rear of the fender and slide it back slightly to unhook the tabs and remove.
5. Remove the nuts on the top and bottom of the VR and disconnect both wire harnesses. Here is the VR completely removed.
6. Put all parts back on opposite of removal.
