The belt's still sound. Oil is full & clean. Radiator fluid is full & clean. I checked the gauges when the CEL came on and everything appeared normal. Power steering did go out when the power stopped being transferred to the wheels. Transmission fluid was full, but a light brownish orange - like a fresh oil. My first thought was trans, as the engine was still running while the wheels ceased to turn. However, when the engine wouldn't turn over, I began to doubt it.
