definately a fuel problem, next time you check voltage at the injectors ground the neg lead to the engine and pos to the positive side of the injector ( the injectors share positive and are negitive fired off the ecu, so the positive will be red on every injector) it could possibally be a corroded harness to the injectors.

It sounds like its losing power to the fuel pump when the key is released, which happens when the EEC relay or the fuel pump relay loses power. The ECU is a common culprit for this. Pin 22 on the ECU should have uninterrupted power coming from it during engine start up. Should be a tan and light green wire which splits off and goes to the diagnostic plug located on the drives side fender near the master cylinder and the fuel pump relay, which should be located under the driver seat below the carpet. Pin number 1 on the ECU should have uninterrupted power as well. The ignition switch might cause this as well, but is less likely.
Do you have a spare ECU that you can borrow from someone? This was a somewhat common problem on 87-90 Mustangs.
Unfortunately, I don't think codes will help at all in this case. Try following the wire diagram I linked below.
