First thing: Drain your water seperator. If that fixes it, replace the light behind your "water in fuel" warning light. If not, replace your fuel filter.
Second: try running injector cleaner through tank, may be clogged injector... if not, may be bad injector. Cheapest solution for this. At the same time check your air filter.
Third: Before you pursue the injector's further, check the fuel pump.
Because of the nature of diesel engines, for it to die suddenly indicates you are having some sort of fuel delivery problem.

For a non computer controlled diesel to die suddenly, it could be a fuel problem. Due to the nature of the powerstroke where the computer is involved, I would put money on a cam position sensor. The computer uses cam position to fire the injectors like the distributor in a gas job runs off th cam to fire each cylinder. It craps out via bad sensor or loose connection and the truck simply shuts off because the computer doesnt fire the injectors anymore. They are a known problem in the 94-98 powerstroke diesels. My friend with a 97 3/4 ton had the exact same problem and changed the cam sensor. He also had to change the cam sensor 3 times in the life of the truck. I would put my money on cam positions sensor. Also, check the codes in computer.

If it is sputtering when it dies, and then it restart immediately after it dies is what a cam position sensor (CPS) does. The cam position sensor is notorious for going out on the 7.3L trucks. If you crank the engine and it doesn't fire and the tach doesn't move that’s usually a dead give away. To my knowledge there is no real way to test them aside from replacing it. When it goes out it may do it intermittently or will just stop, but if its not working the truck won't run. They run $100 or less from Navistar and $160-200 from Ford (same part different boxes). Also keep a ratchet and 10mm socket handy to change the CPS out (use a deepwell 10mm socket with a short extension and a 3/8" ratchet). You might want to carry a spare one with you in the glove box along with the above tools, a lot of people do. They're funny, some last 100k, others don't even make it to 20k.
That is my vote also, a bad cam position sensor.
