What size engine do you have I think you may have a loose ground wire. This will trip the EEC IV relay and will shut down the engine. I will look up where it is located. Both the fuel pump relay and EEC IV relay and ignition switch will shut you down. I had a bad ground on a 85 T-B but it mostly caused a problem getting started. If you have somebody with you get out and put your finger on the EEC IV relay if you feel it click, next try the fuel pump relay.
This will narrow down the problem area. The fuel pump ground should be by the frame back by the tank.
I did a job for a friend and he brought me 3 bad new modules in a row. Did you use a quality module.
When I had a garage the Napa rep. went to a class and they cut them apart. Motorcraft,Napa-Echlin and Standard had all the parts. Some of the cheaper ones didn't. If I wouldn't have had my own tester I would still be working on it.
