Try simple first. Is the tank vent pluged? Try loosening the fuel tank cap and see if it still stalls after 10 - 15 minutes. If not, then start throwing money at it.

No need to apologise Jim,
we are all friends here and we all want
him to have an orange beast of
burden that works right and is reliable
by fixing previous problems that happen
to crawl out from under the seat.

So I drained 8 or so gal. of fuel from my tank, saw no water. Then began removing the draw and return hoses from bottom of tank. When i pulled the draw line from the tank I noticed milky white drips form at the end of the hose. I heard that could be water??? all the lines seem to be clear of and sludge/ debris. I even took a peak inside the tank with a snap-on camera. There was no white residue in tank, and no trash particles big enough to block the fuel line inlet. I removed the two inline filters which were both in the return line from the IP and gave it a new peice of line. I now plan on cleaning the tank and lines with some old stanadyne inj. cleaner, installing a new fuel filter, cleaning the water sep. Then turning the key and hoping for the best.

Just a thought hear but its worth a mention. My L4400 Kubota has a fuel bleed valve located on the injector pump to bleed the fuel system when you change the fuel filter. The manual states that if this valve (jet start valve) is left open it can cause intermittent stalling. Your machine may or may not have this valve but I would check and see. Here is a pic of the one on mine to give you an idea. Its item #80 on the PDF.

You are likely starving and or sucking air on the suction side, have you blown out all the lines? Right after it stalls pull a filter and see if it is dry. Sounds like the previous owner had problems too.
We had an international with this problem for years, finally took the whole suction side of the fuel system apart, the last banjo fitting before the fuel filter had a piece of timothy hay jammed in the little hole. Cured the hard start, hard prime, stalling, lack of power under full load etc.

Had a similar problem with a old tractor. It would run great sometimes for hours sometimes for minutes. It would loose power and then quite. After it would quite I would have to bleed air out of system. This went on far to long till one day I got a bright flashlight and looked in the tank and there was a piece of hose. About 1" x 12" rolling around in the tank. Sometimes it would roll over the fuel outlet in the bottom of the tank and starve the engine for fuel. Very frustrating but a simple fix.:confused2:
