Hi folks. I'm new to the forum. Got a MF243 that started giving problems a few weeks ago. I can't figure it out, so I am hoping for some guidance.
The tractor will start and run just fine. Then for no apparent reason it will shut off at seemingly random times. When it shuts off it won't restart for a few hours and sometimes a few days. But when it does start back up it runs fine.
So far I have replaced the fuel filter which I thought was the problem because it was full of rust and crud. I have verified that even when it won't start the fuel shutoff solenoid seems to be working fine. It is not shorted or open and I can hear it click when I turn the key on. I have also cracked the line to each injector, one at a time to verify all the injectors are working properly. Each injector cause a similar change to the way the engine runs.
I have verified that when it shuts off the fuel bowl below the filter is still full.
One thing that I noticed the last time it started after shutting off was that it didn't start easily like during a normal start. It sputtered a bit like just one cylinder was firing right at first. On the second crank attempt it fired up and smoothed right out.

Today's Featured Article - Product Review: Black Tire Paint - by Staff. I have been fortunate in that two of my tractors have had rear tires that were in great shape when I bought the tractor. My model "H" even had the old style fronts with plenty of tread. My "L" fronts were mismatched Sears Guardsman snow tires, which I promptly tossed. Well, although these tires were in good shape as far as tread was concerned, they looked real sad. All were flat, but new tubes fixed that. In addition to years and years of scuffing and fading, they had paint splattered on
