You should post this on the ECM board. I think the bad injector will knock out the injector driver in the ECM and that's why it dies. After you replace the injector you should be fine, but I'm no computer expert.

Usually fire or fuel. Sounds like the bad injector. If that does not work make sure you have a nice blue spark when cranking the engine over. Ignition module???

I had the same problem not long ago.
If you have a MAF sensor, try unplugging it and see if it stays running. That is the easiest thing to try. You may want to get a book called "TPI Swappers Guide". It has a reallygood troubleshooting guide in it and has helped me find alot of problems. good luck!

Let it idle, open the hood in the dark and look for spark leaks, if none increase rpm to 2K and look again.
I'd also replace the spark plug of the cylinder that had the bad injector.
