I have a 2005 25 hp Johnson that cranks and runs good for 5-10 minutes then "bogs" down and won't get back on plane. The motor can be difficult to crank if you shut it off after this happens. Any thoughts/suggestions? Thanks

2 stroke?
Is the primer bulb tight after it bogs down?
Yes, primer bulb is really tight after it bogs down.
I was thinking fuel related. Sounds like it maybe a coil pack breaking down.
It has to cool down before it runs correctly again
Do a compression test first.
Check the vent on your fuel tank. If it's stopped up, it can produce the very symptoms you're describing.
Check the inside of your fuel lines for decomposition they will crumble and plug it
