I have a 2003 Johnson 140 4 Stroke. It runs great for about 10 to 15 minutes and then acts like its running out of fuel. I can keep it running ( at a low RPM ) and it will motor me in but if I try going to plane it wants to keep cutting out. If I wait a while and start the motor after it sits for a while I can get another 10 to 15 minutes out of it again. As I said the motor runs great from the outset. I can bring it all the way to 6200 RPM. If anyone has a comment I would sure appreciate any advice.
