HELP, Truck Acting Up!!

My uncle has a 1995 7.3 F250.

It will start, throw a check engine light, spit spudder and miss like crazy, check engine light goes off, truck runs smooth as a kitten.

He has his own company and works it everyday, said the other day it did it and he left it running for 8 hours and it never showed a trick.

We put a code reader on it and picks up a code that I can't find online anywhere U3FBFB

It's a very annoying issue.

Any ideas??

2006 F250 4x4 PSD, SC/SB, White - XLT
Sport Package, FX4, S&B CAI.
