I have an intermittent sudden stall and restart,lasting 1-2 secs at low speeds.

What is your question?

The door locks unlock, the check engine light blinks on all electric instruments shut off. It is as if the ignition key was turned off and back on. The gas gauge acts erratic dropping below empty and triggering the low gas warning. I just do not know if it is strictly something electric or not.I have had nothing but problem since I bought this vehicle. 2009 LTZ approx 60,000 miles
