Beyond the concerns you mentioned was the engine running weak or poor?
So far I am leaning most towards a clogged catalytic converter. If that is what it seems like (an exhaust restriction) then remove both upstream O2 sensors for a short windows down test drive. If the power is back then it is one of the converters clogged.
