Took her for a run today…..

[charlie_the_tuna]

She ran like a dog without a leash! Ran like a mother father for a half hour. Not so much as a hiccup. Then, BOOM!!! Started acting up again. Plan on going out tomorrow. Gonna swap out the small filter element and run outside for bass. They***8217;re killing 40-50 inch bass in 10 feet of water. Snag and drop. I have yet to try out my new setup.
So what would cause her to act up after running perfectly for half an hour?!?
My wife googled it and says it***8217;s air in the fuel line.
