Sounds like something is shorting out. I would start by cleaning out the lighting switch at the base of the steering column. You can inspect the wiring connections at the same time. There is not a direct connection between the lighting circuit and the ignition circuit, so if the lighting circuit is the culprit, it must be drawing enough power to shut down the ignition. It is possible there are multiple problems. But then again if it was a dead short it would (or should) blow the lighting circuit fuse. Also will need to check for voltage all the way along the wiring starting at the main power connection at the fuse panel, then the ignition switch, then the gauges and the ignition resistor. The lighting circuit should be hot all the time.
