2.5L hesitation after 30ish mins then runs fine

Fixed 10 pin connector, not the issue, just a thought could the excessive blowby be causing my engine to bog and stall and if so would it make it difficult to start again? Until it sits a bit? Changed oil to 15w-40 don't get as much blowby but still getting it. Plugs were fouled changed those engine seems to run oaky on muffs at high idle without the blowby tube right up to it but haven't tested it in the water yet pic of current blowby slow drip

*Update*

Blowby has stopped since running the engine for the second time since change the oil to a thicker oil.

Also did a compression test had 120,130,130,130

Im going to change the coil and the condensor and see if I can take it back out and see what happens, I'll try to determine if I have a spark issue when warm or a fuel issue of it happens again.

EUREKA!
2 part issue, noticed my inline fuel filter was empty while running on muffs, looked in the tank and found a plastic seal piece to a fuel treatment bottle that got lodge in the pickup elbow removed it, ran the boat still starving for fuel noticed in inlet side of my inline fuel filter had collapsed inside the rubber hose, I guess due to the suction of the plastic piece being lodged in the elbow. That's why the boat would run till the line emptied and wouldn't restart till enough fuel dripped into the line.

Thanks everyone for your suggestions this has made me very more knowledgeable about my boat. Ended up changing the coil anyways one less thing to break down the way.
