Loss of power

I have an 07 24 ssv launch. Went out on the lake two weeks ago and she ran fine. Tried to go this last weekend and for some reason had a loss of power.
As i throttled forward the boat would start to plane but then with throttle still halfway it would lose power. At one point while losing power it kicked back in and began gaining speed, then began to lose power again. Could this be more or less a fuel line issue, or am i looking at something more. Thank you for any information.

Might be water in the gas. Do you have a separator?

Thats a 13 year old boat. Have you ever changed the fuel filter? Can you check fuel pressure? Pump may be on its way out also.

I have an 86 and the fuel line is in the front of the fuel tank so when I get down to about 5 gallons of fuel it will run at no wake speeds but when trying to get of plane it dies. just a though
