I have intermittent starting problems that seem to be fuel related. When it starts it runs fine, and at times it will start with no problem.. However, most of the time when I shut the engine off for a small amount of time it will take a ~very~ long time to start. Just simply turning over until eventually it will start and run fine. It is quickly getting worse, and I have checked most everything out... I'm running on my second fuel pump as well..
