95 GS N/T Kills Randomly ?? Help

[95talonracer]

I buddy has a 95 GS 2.o auto N/T and when you start it, it runs great but it will randomly kill. It seems to be something electrically. We put in new plugs, Wires, Gapped Plugs right, and when it kills the lights and everything on the instrument cluster shuts off and then turns on in a few seconds. It will crank over all day but will only fire and start when the lights in the dash light up at the same time. Help is appreciated.
