Eventually I received the code P0203 - cylinder #3. Again, same short-lived symptom and then moved on. This one actually cleared itself. I did not need to clear the code.

Here's the common thread to both codes - I was towing my 4000lb boat both times. My initial thought was that I must have had some gunk in the fuel tank that worked its way up and worked its way out. But why would that only happen under load? Any thoughts on this?

Thanks!
