Check your battery connectors and make certain they are tight.

And of course any time you change things recently like that and have an issue like this, you need to go back and double check all your connections again. Make sure your wires are on nice and tight.

Could also be a fuel delivery issue. When I had my 8, things like that would happen from time to time (every 5 or 6 months maybe?). I never worried about it until it did it more than once or twice through multiple driving periods.

Check your sparks and wires make sure you did everything right.

Also check the battery is connected tight -- this is your problem IMO

If it isn't your battery connections, describe "car dies" more accurately. Suddenly shutting off everything (engine, electrical) completely, absolutely abruptly like a light switch...that is always a battery or wiring problem.

If it just died like it stalled out, you are looking more at fuel pump or fuel starvation issues.

If it struggled to stay alive, but still died, that is probably ignition and/or catalytic converter.
