03 Johnson 150 2 stroke issue

My motor runs great when I first crank it and run down the lake. No skipping, hesitating, etc. The problem is when I stop to fish for a while and recrank the motor it cranks fine but when I give it throttle it dies out. Sounds like it is starving for gas. Bulb on fuel line is not completely hard but firm. If I pump it a few times the motor will eventually take off and runs fine until the next time I stop for a while.
Any thoughts on what could be happening?

Have you checked your fuel tank vent? Is it closed or clogged

Possible bulb going bad.

Double D.

Have not checked that specifically but when filling the tank I hear a noise coming from the overflow vent on the side of the boat.

thanks

Just put a new fuel line with new bulb from the tank to the motor. I was having this problem before I did that. I was hoping the new line would solve the problem but made no difference.
