Then something has to be shorting out somewhere, that is killing the engine. You can download the factory service manual from this thread. Wiring diagrams are in section 8W. Need to figger out what you are losing when you turn the headlights on...... since everything I know about diesels is written on the inside of my left eyelid, that's about all the help I can be.

Something shorting to ground interrupting signal to PCM?
I would inspect your headlight switch and wiring at the switch, and also figure out why the blower isn't working - bad blower resistor? Does it only work on full or not at all?
I've got so many wiring schematics running through my head I can't remember what's what, but it might be Dodge that I'm thinking the switch operates on the ground side, in which case if you're losing ground behind the cluster it might explain both issues.
