Did you check battery voltage after driving it? I've driven over a hundred miles with a bad alternator, but the truck never died as long as it was getting fuel. But then I'd shut it off and the batteries would be totally drained.
If your batteries are okay but it keeps stalling I would look to the fuel system. Air in the lines, dirty filters, etc.
