Hi,  
  
 A few years ago it developed a problem of shutting down right after it starts. It is intermittant. May shut down up to 30-40 times in a row. It starts,coughs, then stops. Eventually it runs fine. A real pain. Have had several mech’s look at it. None have found the problem.

You need someone who can check spark, fuel pressure and fuel injector signals when it’s not running. Then figure out why one of these is missing.
