    I was wondering the same thing. Do you know if your gas has ethanol in it?

    Check out this link to a post from a few weeks ago:

    Jason, do these symptoms sound like the ones you saw before you experimented with the gas?

    Are you holding pressure in your fuel line bulb?

    Does it crank easier if you pump it after you run.

    Start with the simple things.
    Give a man a fish, he will eat for a day

    Teach a man to fish, he will complain that you stole his fishing spot.

    Just had a 225 V-Max do this. It was caused by two things. The O2 sensor had n it. Yes I run ring free I might skip a tank here and there. It was removed and burt off with a torch. Also had two fuel diaphragm leaking. Hope this helps.

    Change the lift pumps. You can rebuild the pumps as well, but the entire pump only runs about $40 each new.
