I was driving my honda accord manual 1990 model when I noticed that the gauges were dancing, though I was still running. Then, when I park for about 15 minutes and started the engine I won't start anymore and I notice that dash board lights were gone and there's no way the engine would start, what could be problem any help please?

Check or replace the ignition switch for wear, pitting or melting:
