Recreational Vehicle Lpg Tank Valve/gauge problems of the 2013 Chevrolet Malibu

All electrical inside car goes out or on and off while driving. All dash gauges, speedometer, gas gauge, radio, heat/ac, turn signals, etc. Car still runs but nothing on inside works. I do not know if this control outage effects the abs or steering. It only last for a few seconds. It has happened several time will drive 50 to 70 mph. I've let off the gas and try not to panic. Everything comes back on and I continue home. I'm scared to drive my car.

While driving and going to change lanes, I turn on my turn signal to change lanes and the power steering stops working, the dash gauges flicker and the radio cuts out and sometimes the motor cuts off. This also occurs when sitting still, the steering wheel will bounce if turning one direction or the other. I have seen many of these complaints online and no resolution. This also happens while turning. This happens every day.
