While driving, all dash lights come on, engine starts to cut off, door locks off

Hello, I highly suspect the electronic portion of your ignition switch for failure. With the car parked, turn it on and see if slight giggling of your keys will make this happen. Also, notice if you turn the key to the ON position without starting the engine, it will have the same characteristics. I think the ignition switch is losing contact and turning off for a split second. It is likely recovering after the engine and transmission control modules run through their self checks.
