1998 Izuzu Hombre will run fine then all of a sudden the motor shuts down.

What is your question?

When this happens, the dash lights go out but the headlights still work and the motor will crank over but not start? I have pushed/pulled wires in the steering column and played with switches. Nothing seems to work except let it sit after that and it will start. Relay getting too hot? Where would this relay be that controls the dash and power to ignition only? Thank you
