Hello Folks, chasing a ghost on a 2017BF150A Honda. I have a problem where after running the boat for a while turn off engine come back an hour later crank but won’t start. It will eventually crank wants engine cools down. When it does start boat runs like a champ. I can recreate the issue pretty easily. Ride for 20 min engine gets hot turn it off let it sit for an hour won’t start.

There is spark which led us down a fuel problem or cooling issue

Brand new impeller
All fuel filters replaced
New Batteries
New fuel lines
Replaced neutral switch and throttle
Replaced main fuel relay
New Ignition switch and key ( Thought it was electrical)

Latest diagnosis maybe a vapor lock issue which lead to all new fuel lines and filters. Throwing darts at this point. I have found some threads about a potential issue with the high pressure fuel pump. Not sure if the boat would run great after start with a high pressure fuel pump issue or not. Any ideas ?
