I have no idea why you are having issues now, but I am curoius why are you warming up engine at idle instead of bumping it up rpms to something like 1200-1800? Leejohn has the right idea though -- was TWO diesel filters replaced on invoice? I'd check the one underneath first and compare it to the color by engine. The bottom filter is "exposed" to the elements and not warmed up by block heater. The filter by engine MIGHT get some sort of radiated warmth from engine block heater unless its windy where tractor is stored. If you have treated your feul - I'd pull out a sample and look at it in a clear glass jar .any crystals ? waxing. I'd put 911 in it. Are you sure the tractor is shutting off from the gelling or one of the tractor safety interlocks? Pull back on pto lever while trying to start, wiggle hst, etc. I'd would also glow the plugs a bit more then 20 sec like 30 secs or cycle glowing twice before starting if it really cold.
