Turbo stall on Diesel engine

As the turbo is driven by the engine exhaust gases, I'd say it was the other way around.

Turbo stall occurs when the throttle is closed, and blocks the air from exiting the turbo, thus stalling it.

as a diesel is not fitted with a throttle plate, no turbo stall occurs on a diesel engine.

It could be overboosting and getting shut off maybe? I'm not familiar with Ford diesels, but VAG TDI engines with a VNT turbo will exhibit this, and log a fault code- 'overboost detected'.

Yeah, that makes sence.

So, on a normaly well-behaved vehicle, what could be causing that? I'm guessing either fuel injector issues or fuel starvation for a different reason?

You havent got an intake hose sucking flat have you?

AFAIK the DE doesnt use a vacuum operated throttle valve, but if it does check it.

Tim.

IIRC it is actually possible to stall a turbo without shutting the throttle, by mismatching the turbo to the engine - turbo spools and effectively over-produces boost, falling outside its efficiency range and stalling the turbine until the engine catches up and devours enough air. I'm not totally up to speed on my fluids but i did have it explained to me at some point in the past.

Does the turbo have a waste gate which is vacuum operated? If so is the vacuum control solenoid working properly, and are the vacuum hoses in good order? If the waste gate is not opening when it should you could get an overboost as stated above.

Nope, but I do have a rusty line to the injector at Cylinder 1. I wonder i there's a pinprick in it?

You'll see the fuel wetting it if there is.

Well, a Fuel Filter change, a one shot Redex in 1/4 tank and 130 hard miles seems to have resolved it.
