When you say, "lose power", do you mean it's as if you took your foot completely off the gas? If so, I think you're on the right track. Fuel. I had a similar problem with an old car a LOOOOOONG time ago, so take it for what it's worth. My problem turned out to be the fuel filter, but if you've already checked that I would next look at the fuel pump.

If the power loss in intermittent or less drastic then you start looking at air filter, vacuum hoses, etc.

I've always believed in the when-you're-confused-replace-something-cheap approach.

Good luck!
