Check fuel injectors for power when it dies. Also, make sure the fuel pressure is maintained when the engine dies.

You must be losing fuel pressure then. When it dies, check fuel pump pressure. Also, double check the fuel pressure regulator. If it starts and dies with starting fluid, that tells me it's losing fuel. NOTE: Also, check to make sure there is power to the injectors when it dies. You can use a noid light. It will pulse on and off as the injector gets power.
