intermittent issue starting dt140hp

[ravioli_fishing]

I own a 2003 Suzuki 140hp outboard. Recently my engine will start fine, but after fishing in one spot it will not want to start. If I wait 20 to 30 minutes, it will then start with no issues. This does not happen everytime I go out fishing. I have owned this engine for 9 years with no problems. I have already checked my gasoline and fuel line. Any ideas as to what could be causing this issue?

only a blocked vent on tank comes to mind

sounds like it gas starved sucking in just enough gas to stay running but when shut down its in a vacuum so it cant suck enough gas to refill the bowl to start.

after the 20-30 minutes it equalizes pressure so it can suck in gas to restart

try it with the gas cap off and see if it restarts

Great I will try your suggestion and think the gas cap is a really good thought. I will try and get back to this thread if it resolves my issue.
