New to the forum! I have a 2012 yamaha f40la I've had for a few years it ran fine when I got it then maybe a year ago it's started this.. fire it up it runs perfect for about 12-20 minutes then it's like it is running out of fuel jumping and skipping, pump the primer bulb it really doesn't help it skips jumps slowing down until it'll slow down to less than 10mph I've change the fuel separator on the back of motor with no effect also new fuel lines and has never had ethanol through it. It does this every single trip idles fine to about 1/4 throttle. Any help appreciated. Having trouble uploading a video of it.
