My Caddy 2002 keeps stalling at different times. This last time (Saturday night) I was on the freeway in the middle of 10 lanes of traffic, dark and the car just died. No lights; no power, nothing. I managed to get to the side of the road and was able to restart it again. This has happened about 10 times in the last 5 years and I have paid to have it repaired about 4 times paying about 340 each time. At first they said it was sensors and now they say it is the ignition. Very frustrating and scarrie on the freeway.
