Back to basics. When it will not start, have you pulled a plug to see if it is wet? You can probably tell if things are grossly too rich as the plugs would probably foul pretty quickly. Was the exhaust sooty and black before it died?
Will it start with the accellerator floored? I think this still tells the engine not to dump fuel and is recommended if you think the engine is flooded. So you might try that as well.
Going the otherway, is it possible your nitrous kit is not playing nice with your fuel pressure regulator? How is your fuel pressure? I can't see the original message right now, so I don't remember if you mentioned verifying this.
Might want to back out the nitrous kit to see if things don't return to normal.
Just a couple of back to the basics, as I've never done the 3L swap.
