2000 150hp OX66 bogging

[Offshore_life]

While heading out to fish I was running
4500 rpm . Then all the suddenly the motor
Bog down to 200 or 300 rpm and die out . It was like staving of
Fuel. The primer bulb was soft . Got the motor started limp to fishing area .
Fish for few hour . Start the motor up and everything run fine again.
Oh yeah before I head out . We stop to get some gas about 10gal my friend didn't know and pour a whole bottle of starbrite fuel treatment in .
After searching and reading I decided to change out vst filter and
Send injector of for cleaning . Is there anything else I can check
For bogging issue any info will be helpful .
Thank

testing things like fuel pressures/ vacuum and electrical would be better than guessing

Regarding to motor bogging down. Majority of them was solve by changing
the vst filter . I will check with a marine machanic regarding to all
