I have an 02 Grand Cherokee with an inline 6 cylinder. At random times, the Brake and ABS instrument panel lights come on, and the voltage (show on the gauge) will sway from about 10-14 volts. If I continue driving , the car dies. But after shutting it off for a few minutes, it starts and runs just fine.
I've had the vehicle for about 5 months, it has happened 4 times. The dealer has looked at it, but the problem has not occurred when they had it, so no help from them.
