I'll give you my two cents. My 226d had the same symtoms as yours.
I noticed this black like slime in the fuel filter. I took of the hose at the tank and nothing came out, then I saw this black like slime blocking the way.
I decided to do the right thing and remove the tank. It was a slight bit of pain, as I had to remove the steering wheel, disconnect the electrical connections, the ignition switch, decompression lever, tach cable, disconnect the power shift. Once I got the tank out, I drained it completely, filled it with some diesel and shook it violently, drained it again, repeated that process a few times, then drained again, and this time put the air hose inside, and blew it out from both the top and the where the diesel line hooks up.
After I put it all back together , it runs as if new. Not one miss, feels stronger than ever.
I'm not sure what the black gunk was, but I am most sure that was clogging the line thus limiting fuel and causing air to get in the line.

I had the same issue. When I bought the tractor it had been sitting for a year. ran great in the dealer parking lot. until I brought it home. I drained all the fuel out of the hole system and cleaned everything and changed filter,removed some fuel line that someone had spliced in. just after pump to just before the tank(return line
).couldn't tell you what the thinking was behind it..??

Wow! YM2000 is far simpler.
Drain the tank and take off the fuel return hose. Then unbolt two tank straps and remove the fuel outlet hose underneath. Lift out the tank. Two minutes max, after whatever time it takes to drain the tank.
I discovered a flat piece of transparent varnish (or maybe plastic from a fuel jug) the size of a whole fingernail fluttering near the drain hole in my tank last time I drained it. It hadn't caused a problem, but it looked like it could have.
That black gunk sounds like it was made by the diesel-loving bacteria that can live at the water/diesel boundary when there is a small amount of water anywhere in the system. It is famous for plugging fuel filters.
