The fuel pump may be on its way out.

When was the fuel filter last changed?
A dirty fuel filter will show these symptoms when a high demand is asked for.

Also check that the air filter is clean.

thank you for your response.
when the problem first accurred, i changed the plugs, but yestarday, i changed the fuel filter (and that was long over due), aswell as the air filter, a vacume hose, and the filter going to the crank. my problem has been an issue for about 6 months now.
