On a post note after sleeping on this problem, the sediment bowl had crud in it.  The combine ran fine until I moved it.  That is when the problems began.  From the YT board comments, I think the next step is to drain the gas tank, remove it and have it boiled.  I am guessing the fresh gas is slowly stirring up what is left of the old varnished stuff since the fuel strainer was packed with "playdo" and a lot of green stuff washed out in the first 10 gallons of gas when I flushed the tank in late November.
