Service Engine Codes for a 2011 Malibu with Monsoon 350 and CAT ETX

Our family vacation this week can't go over 30 mph.  The boat used to occasionally send an error code of Service Engine at idle.  I would clear it and boat always ran fantastic.  I pulled my son skiing yesterday and it struggled to get above 30 mph and sound rough, like backfiring.  The error codes below showed up on the ECM.  Any ideas.  It has almost 300 hours on the engine and my research shows a likely culprit could be one of the 4 02 sensors on the CAT XTC.  Other than wiggling them around like a moron, I have no good ideas on what technical steps to take next.  I keep it on a lift and the trailer is 300 miles away.  I appreciate any advice you can spare.  Thank you.
