defender 2.5 n/a diesel cuts out like it has water in the fuel

Hi...what could be causing the problem in my 95 defender 2.5n/a diesel engine?? I drive for awhile, somewhere around 15-20 min and the engine looses power and spits and coughs like it might have water in the fuel, but, I drained the tank and it still acts the same. Some have said it could be air getting in somewhere and doing this. Please, if someone has experienced this and was able to fix it, could you let me know. The defender works well for a time but then does this and the frequency of it happens much more often once it has done it the first time. Very frustrated. I am not a mechanic but am willing to learn .
Thanks for any help in advance.
Wayne

Maybe the fuel pump isn't working well? If you open the bleeder on the injection pump and work the lever on the fuel pump, does any air come out or does fuel come out?

Step one, check that the lift pump is working. Disconnect the fuel solenoid wire and the inlet line to the fuel filter. then crank it over and see if you get a good flow of fuel. If that is good check for leaks that could let air in.

Do you have a sediment bowl filter at the rear? Does it happen when the tank is full or empty or doesn't matter? Do you have the metal tank or the plastic? As advised above I would check that out first. But if you find no problem start checking the other stuff mentioned. I would also make sure your vent line is clear.
