suggest disabling anti-theft alarm module for test

To determine whether the anti-theft alarm module is disabling the fuel pump relay and inhibiting your ECU, try pulling the Fuse #16 in the electrical distribution panel under the passenger side airbag.(NB I've just looked at the wiring diagrams for late model cars, 95 -98, you may have to find this fuse on your '93 model). Fuse 16 is hot at all times, 15A.
The point here is that a missing ground would cause the doorlock circuit and anti-theft circuit to misbehave; after pulling the fuse, if the engine no longer cuts out randomly, we've found the reason. The fuel pump, ECU and TCS module are powered through Fuse 13 (Circuit C, green-white wire, from the RUN position of the ignition switch, 10A). Good luck.
