Mercury 90 HP 3 times

I have problems with the Mercury 90 HP 2T engine, regulates and lights perfectly but at times when I am navigating, it is only as if it runs out of fuel, obviously, it verifies that it is not that, but it is that same symptom. Change the fuel filter and sometimes it does more often and sometimes not so much. I wanted to consult if someone can give me an idea of ​​what it can become.
Greetings Thank you
