Weird ignition problem...maybe!?

I would buy a new NAPA (don't get the cheap Autozone, Advance, electronics) control box and switch it out. If it isn't that then you can say you got a extra control box just in case you're on the road and it dies. That immediate death sounds like ignition problem to me.

Oh yeah check the bulk head connections there on the firewall and other connections. Make sure they are clean etc...
