Sounds like a bad O2 sensor[s] to me too... I had one go south on a domestic -- took several months to totally fail.
When it first started throwing CELs, it would only happen when I was pulling long hills with steady throttle. As soon as I topped the hill and backed off the throttle, everything was fine until the next time.
This happened more n' more, over probably 6 months, until I finally got tired of it and replaced the primary sensor -- end of problem.
