F115 stalls at low rpm

[Toyelectroman]

Hi, I have been having an intermediate problem on my 2017 F115 where it will stall at idle or in gear in a no wake speed. Doesn't happen all the time and usually only happens when the boat has been off for a while . I have fresh gas, replaced fuel filter, and water separater.

When it does happen I can pump the primer bulb to keep it from stalling

my guess is the fuel cooler is plugged or restricted causing the fuel in it to vaporize.
maybe you need to let the motor idle for a little while befor shutting it off after a high speed run to let the motor cool down some
