I find it hard to believe that any 12 good citizens of Texas would find that, when a stranger who had aggressively acosted you returns with another person and a visible firearm, you were unreasonable in your belief that he meant to do you grevious bodily harm that could cause death. At this point deadly force in your own defense is legal.

Tactically, I agree that moving the vehicle to a safer location is your best bet. People have been killed by careless, inattentive and drunk drivers while trying to work on cars broken down on the side of road.
