why are my dashboard indicator lights flashing on and off and all gauges die? on 2005 Jeep Grand Cherokee

while driving all dashboard indicator lights flash on & off, gauges MPG, engine, RPM and gas go dead & exterior lights flicker.Comes back on but sometimes the fan blower will stop. its as if im just starting the car. I have new starter, new battery and new clutch fan. please advise?
