RPM's drop to nothing and won't start backup
 

I was driving down the street and all of a sudden the rpm's just drop down to 0. I try to start it back up and once I trun the key, nothing lights up on the dash, and the car won't even try to turn over, but everything works that has to do with the battery except the dash.
I think it might be the starter relay, or the ignition switch. Anyone know what it might be?
Thanks, Kris

Sorry, it's a 90
