Hello, this is my first post.
The issue, while out on the lake yesterday the motor started to lose power. Would run fine at idle but would 'choke' when I accelerated. Shut down motor, started again in one pull and problem was gone. Then it reappeared about 5 minutes later. Shut down, restarted and it works fine. I assume fuel problem, This is a new motor for me and is only the second time out.
Fuel and oil are new. Idle Mixture Screw is set correct and is clean when I pulled out. Filter (screen) on fuel tank is clean. Plugs look good.
Any ideas on cause and fix would be appreaciated.
Thanks in advance.

I pulled Fuel Bowl and it is clean like new, no residue at all from sitting gas.

Update:
Fuel filter is clean.
I did locate on small piece of debris in the float bowl, could this have caused the problem???
