I removed the batteries from the remote and left the IR port on the amp uncovered. The amp repeated the change-- selecting another input with no action by me. I then looked for another IR source that could be causing this and remembered my IR-to-RF converter.
This device effectively extends the range of any IR device by inserting an RF transmitter into the battery compartment of the remote, and then duplicating the IR codes to the hi-fi unit. I've had it for many months and forgot about it. I also am not using it with the amp, but instead use it with my Squeezebox player, so the converter is only sending SB IR codes.
The IR extender has options to transmit on 3 frequencies, so I selected C when the unit had been on B. It's been a few days and no repeat of the issue. Amp seems to be working normally and I can still change Pandora selections from anywhere in the house.
Odd that I've been using my system with the extender with no issues for many months and only recently did this issue appear.
Here's the Amazon link for anyone interested:

Thanks for everyone's help and encouragement.
