You're going to have to determine what is dropping out when it dies, either spark, injector pulse or fuel pressure. This is not adding up. Fuel pressure and security systems are the things that act that way.

Is it the power side dropping out of the ground trigger side?
Also be sure that the spark isn't dropping out with it.

And are you sure that the spark is not dropping with it. Did you see any spark after the injector pulse had dropped out?
