Intermittent power loss, fuel filters or something else?

Recently I am experiencing some power loss in surges. I mostly notice it on the interstate. My filters are both fairly new, less than 6 months. Although I am running on a diesel tank now, just before this I ran 2 or 3 tanks of 50/50 diesel and filtered WVO. It ran fine on the WVO and has just started doing this on the diesel again. I wondered if the WVO knocked some gunk loose and I need a filter change or if this sounds like something else. It may not be related, but my fuel gauge has also started flickering occasionally.
