So I have the engine running so I can bleed the air out of the power steering just installed and the engine just stopped for no reason. All systems are dead, lights, horn, ignition key, no power to anything. So what is the most likely problem. The battery is grounded and charged. There is power at the alternator. When turn the ignition key nothing happens, no clicks turn signals, everything is dead like there is no battery in the car. Is there a fusible link someplace need to check? In all my years have never seen anything like this. One minute running fine, next dead. No burnt wires or burnt smell suggesting a dead short.
