I pretty adamant you have contaminated fuel. Drain and re-fill with fresh fuel before you do anything. As you have driven it you may find you need a set of injectors. They are not cheap. Drain fuel, new fuel filter first and see how it is after.

Fuel contamination in Diesel engine is potentially a major issue, because Diesel fuel is in fact oil and it is used to lubricate the high-pressure fuel pump and the injectors, and without this lubrication, these components may suffer (expensive) damage.

Does the diesel and water separate in the tank sufficiently to drain the water off from the bottom without having to drain the diesel? Have you ever tried an additive to aid that?

Its best to drain the tank completely. Often the water is not pure and has all kinds of debris in it. Drain the tank. Do it properly once.
