I've not seen any codes when mine did that. At least I don't recall there being any

Do you know of a fix??

Did nothing. It always self corrects when it sees the right conditions. IE: fuel level going down

Did find code p0461. Cleared it and it changed nothing. Ugh! Normally don't daily drive the truck but think I will just to see if it will clear itself. On edit, roughly five engine starts after clearing the code the fuel gauge started acting normally. With my next haul I'm going to try the above filling suggestion, start with ¼ tank or less and stop transferring prior to ¾ tank. Fingers crossed.
