Car trouble....
I'm runnin out of ideas here

Maybe, this is why you are not getting replies??
that pinpoints it to electrical as opposed to fuel at least,
the fact you have no electrical power at the gauges and no lights further pinpoints it between the battery and the ignition switch, if it were after ignition switch then engine would shut off but you would still have lights and gauges would work.
I hear the mid-1990's cars had fusible links inline in the wiring, buddy blew his on his 1995 camaro, although i think once they're blown that's it they're done. your problem sounds like something may be heating up & failing, cooling down then working so look at relays, otherwise loose wiring or bad connection in the place i mentioned, and on the ground side between battery & engine block/metal body.
by the way, wrong ******* forum
