My M5700 starts and idles fine, but when I put any load on the engine, especially in a higher gear, it dies unless I rev it way up. And even revving it up won't get full power. It does not go above about 2000 rpm. I have replaced the fuel filter, checked the fuel flow, cleaned the air filter, checked mechanical links. It just does not seem to be putting enough fuel into the engine. I had my mechanic neighbor take a look and he is stumped (admittedly, he does not feel all that comfortable poking around modern engines).

Sounds like the pump isn' suppling proper fuel pressure. It could be tested on the tractor but it is probably easier to remove and take to a reputable shop and have it tested.
