Help, it won't start

Another car I had would die in the middle of the street and it had no warning.  I had traffic tied up for blocks because it died near a construction zone and not one person came to see if they could do anything.  After about an hour it finally started and off I went.  Upon taking it to the shop the guy couldn't find anything wrong with it.  It left there just as bad as when I brought it in.  I got out of work one night with all the others and when I got to the light it died.  I went to the motel across the street and called Bob.  He couldn't believe no one would stop.  They stopped to flip me the finger or throw up their hands like it was my fault.  I did learn how to keep one foot on the gas and one on the brake when I was going to stop.  Someone finally figured out it's problem and it was all better, till the next thing broke down on it.......
