Finally addresed the issue by replacing both solenoids. Parts were ~$80 each. Labor at my indy was only about 2.5 hrs.
Before having the work done, I had increasing difficulty fueling up without the vapor pressure sensor or whatever fighting me at ~3/4 of a tank. First auto stop would be 3-4 gallons less than full. That problem stopped after replacement of the evap solenoids.
