1985 Force 85 motor bogs

1985 Force 85.
Purrs like a kitten at idle. runs up to ALMOST on step. Any further advancement on throttle, and it begins to bog down. If you let it, it quits, but starts right back up. Reduce throttle and it won't.

Ideas?

Sounds like the tank vent is blocked.
Possible the ethanol has softened a hose and it collapses and shuts off the fuel.
What kind of tank?
 
The same thing happens to mine, (same year same model) when i started to call around for new fuel pump kit the parts clerk at the boat store suggested testing compression first the these other tests below, before replacing things, not sure if its true but my compression tested 120 on each cylynder, which i hope is ok,someone suggested the below does anyone concur?
Test #1 Start put in gear and take off until it starts to bog down, then
pump bulb rapidly

if it continues to stall then u have fuel pump diapram problem,


Test #2 Start put in gear and take off until it starts to bog down, thenpush
in choke if

it does not die then you have carborator problems,
