Ford Repair: vapor lock, vapor lock, electrical problem

Question
I have a sable 93. It only has 63,000 miles. The last month, twice after driving 60 miles, it just stop, and I waited for 20 min. and its started right up, then two weeks ago, I went 15 miles, and the same thing happen. I was told it is vapor lock, any advice on what to do? thanks, tom  

Answer
Im not sure, thats a pretty vague problem.  Something could be overheating, and it could very well be vapor lock.  Could be a lot of other things too though.  Its pretty rare for cars to just stop while there running unless they bog down or run realy shitty, so it might be an electrical problem if the car just seems to die out for no reason.
