I am trying to tell you, you still have a problem with water getting into the intake. The reason it runs for a short amount of time, is the plugs are dry. It stalls out because the water is being pulled from the intake, and quenching the cylinders, and thus coating the plugs. Do you have access to a cooling system pressure tester? Pressure test the cooling system and see if it holds pressure. The consequence of doing this, is that you may create a hydrolock condition again. I am almost certain, that with the condition that you are describing, you have a failed upper intake, it has a hole in it. It is not too much trouble to remove the upper intake, remove it and look for water on the top of the lower intake. I went through this same situation with the Oldsmobile that I referenced in the first post. I replaced plugs as well, only to have them foul shortly after.
