I wanted to follow-up on this post because I determined what the problem was. The issue is caused by heat affecting the O2 sensor. During the summer, the heat from stopping for gas or other brief stops caused the O2 sensor to read incorrectly. With the colder winter temps, the problem has gone away.

I do not have a heat shield and I figure I need to add one before summer to keep this from happening again.
