580D backhoe losing power under load

[Adrian Billheimer]

Hi folks, I have a Case 580D backhoe w/207 nonturbo, yesterday while I was digging out an old footer the engine started lugging real hard while operating the hydraulics, so much that when I was lifting the out rigger, I had to stop twice or the engine would die and this was from full throttle, then as I was moving the tractor the engine was running rough.
I'm guessing I have a problem with the injector pump, any help will be appreciated.

Sounds like fuel filters/water seperator need to be changed.
