Will it run WOT for 15 minutes straight? (at 40 mph) If you have a friend constantly prime the fuel hose bulb, does it make any difference when it's bogging?

The thing will run wot up to about 40 mph. Then when I stop sometimes it will bogg down after it cools off but sometimes it will start and take off no problem

Unlikely the engine would run WOT if it had a fuel problem. You may have an intermittent spark issue.

Do a cylinder drop test on it when it acts up and see which cylinders aren't firing.
