    I had an ignition key switch fail on me before just like this. The car would start and when I let off the key it would die. I just replaced the key switch and it fixed it.

    You said you've upgraded all the wiring recently and when you let off the key the motor kills itself. Based on those two things, I'd double check which post on your ignition you have your coil wire connected to.

    Easy to test, turn ignition switch and test voltage when on, none when off. Trace the voltage. You should have power going to the coil and distributor.
