Fuel Bowl not getting fuel.

Fuel Bowl not getting fuel.
My 1999 7.3L Stock everything sputtered on me one night when I got off work. I drove to the station and filled her up. When I started it up at the station she sputtered again. Drained the fuel bowl and restarted the engine. Still sputtering as I got on the interstate anad she started running fine for 25 miles. After I got off the interstate she started sputtering again. Stopped to do a late night workout and she would not start back up. Had her towed home.
The fuel pump is not making any noise. Of course the fuel bowl is not getting any fuel. When I pulled my filter out (which I changed 2 months earlier), I noticed a wire and something that looked like a watch battery at the bottom. Did not bother them, but the little disc is loose. Also as I am cranking the engine, the crank spped is fast, but the tach barely moves. Can the CPS, cause the fuel pump not to work?
What can I check to make sure the fuel pump is bad? I need some guidance.
Thx

If your WTS lights normally, then you may need to use a test light to confirm that your fuel pump is getting power. Keep in mind that the PCM will provide power to the fuel pump for about 20 seconds and then kill power if the engine has not been started....so check for power within that time frame.
If you have power at the pump, then get a five gallon jug of diesel and connect a short hose to the input side of the pump and see if the engine starts. If so, then you have a restriction in the tank..(fairly common issue).
Hope this helps..

Clogged fuel filter or tank screens start with chocking the engine under heavy load. Had both and they take long time before killing the engine.
I had similar to above incident couple months ago. My F450 died on the freeway and I tested it to have empty fuel bowl. After poking around for few minutes and moving pump connectors it filled up the bowl, so after some cranking the engine restarted. Drove about 3000 miles since and it never happened. The only thing I can figure out is that fuel pump had bad wire connection, although my truck has no rust. I was thinking about getting spare pump, but those are pretty expensive.
