I decided to go to a local indy who has diagnostic equipment that could read the ABS fault code instead of continuing to chase the intermittent problem.

I actually began to test the sensors myself. They all showed to be working fine which was puzzling. At this point I decided chasing an intermittent problem could be a long process so I decided to find out what the actual stored fault was. The fault was being triggered by one of the front sensors.
Changed the sensor and no more warning lights.
