[QUOTE="JMichael, post: 362231, member: 7544"] I had an older 3.9 Merc that did the same thing. Problem turned out to be a worn o-ring inside the fuel line connector where it connects to the engine. It was allowing a little air into the fuel line as the fuel pump tried to suck the fuel from the tank. There are a lot of possible reasons that can cause the same symptoms as others have listed some of them so you may end up chasing this one for a while before you find it. [/QUOTE]
