It is possible that the fuel line got kinked if the car bottomed out somewhere hard. The designers usually put the lines next to frame rails and other well protected areas, but it does happen on occasion. I don't think that it is a charging issue (battery,alternator), as there would be symptoms before the car shut off.
You should scan for error codes one more time before sending it to the tech. I wish I could provide more options but if this was my car, I wouldn't know what to check for next.
