Thumbs up to Chaz and Jerry. We tried some of the other suggestions, but they didn't solve the problem. We took the car to Lee and he put the fuel pressure gauge on it. There was no leak down after 10-15 minutes.
Key on only gave it 30-35 psi after multiple key on no start tries. After starting, the pressure was no better, so he had Lee replace the fuel pump with a Bosch pump. Pressure immediately went up to about 44 psi at first key on.
Ray drove it back from Loganville to Auburn, then drove from Auburn to Griffin via Loganville, Social Circle, Conley, McDonough and High Falls. Drove around the Griffin area for the day then returned to Auburn with no problems at all. The surging at road speeds is gone, the hunt idle is gone, and the putt, putt, putt is gone. Initially, this looks like a failing fuel pump was the problem.
