Failed alternator , dying battery. Have it checked. That's a first thought. How often has this happened? Any driveability issues?
it happens mostly when I come to a stop, maybe twice in an hour the Tachometer goes up and down then plummets to ZERO while the engine is still running,(shuddering)The brake warning and ABS Lights flash the AC also shuts down.
If it's never left you stranded , with a dead battery , then going by your further description , I would suggest troubleshooting the idle circuit.
