That fault is caused when the ECM doesn't see enough change between the front and rear O2 sensors. You could have a bad/slow front or rear O2 sensor or a bad catalytic converter.

I don't know but I suppose it's possible. If you haven't already, I'd clear the code and see if it happens again after a fresh tank of gas.
