LMM: LMM Falls on its face, then comes back when I let off and get back into it
Goes like hell for a short time then without fail it falls on its face. I lift the throttle for a few seconds, get back into it, and it goes like hell again. For a longer time then fails again. It's like the fuel gets replenished in the rail then i starve it again. A few times of doing this I'm... -

It happens at all speeds. It's 100 percent of the time under full acceleration in all 5 positions -

I just know nothing about diesels so I came here to learn. I build a lot of cars and gas engines so it's out of my realm. Many thanks for your help -

Also it is pretty smoke free, per my request as well. But it does smoke a little. The smoke stays visible during my issue -

I have an EFI live tune on my 08 LMM with the 5 position switch. When I go "extreme" it falls on its face after accelerating hard for about a block. Then I lift off the accelerator and it goes like hell again. Sometimes. Could this be injectors or other fuel problems? I replaced the fuel filter...
