318 engine just died and won’t start

Greetings!! Started my 69 Fury the other day and while I was letting her warm up she just all of a sudden died. I don't think it's a fuel problem as it was like someone just turned off the ignition. I changed out the ballast resistor and inspected the cap/rotor, but not sure what to check next as she still won't start. Lights, turn signals, etc. are ok. Any ideas as what to check next would be appreciated!!! Thank You
