It's possible the tumblers have fallen in your ignition. I had a similar incident with a Focus I owned. Everything locked and I couldn't get the key to turn at all. They had to tow the car to the dealership and replace the tumblers.

SOURCE: 2002 pt cruiser dies then fires right back up randomly going down the highway

most of the times when the car cut out it is cause by the crank angle sensor you wait for it to cool down and it will fire back up again, best way to check it is to take a bottle of water with you and try to locate (which is between the fire wall and the engine on the driver side on the engine block) where the crank angle sensor. when the car cuts out pour the water on the sensor to cool it down if the car then starts right away that is the problem.

SOURCE: electrical problem; while driving door ajar light comes on

it may be one of several things ...but sounds like the door switch is not completely engaging or it does and after either hitting a bump or just turning the corner it will break contact just enough to let the vehicle think its either open and then shut ...
in other words if you open the door and try using maby a piece of rubber hose and add it to the switch just a tiny piece or if there is an adjustment present to allow the switch to fully complete the circuit it should stop

as soon as you said the interior lights come on should have been a clue to the issue and being made of plastic they tend to wear bend and cause an issue as such .. on some vehicles there is a door panel that has a plastic stopper that meets the switch if yours is like that consider removing the retaining {plastic} insert screw and put a washer behind it to allow the 2 to meet at a shorter throw ..i hope you understand that .otherwise adjust the door switch if possible if that is not possible try a piece of cardboard temporiarily on all doors until you can decide if this remedies the issue and it should if so then consider replacing the switch or switches upon ensuring this is your issue
