Ok so basic info is needed...how many miles on the engine? Any mods done to it? When did you last do a tune up? (wires, plugs, oil change, air filter)...when does this happen the most? When you put your foot into it? When the a/c is on? When your just cruizing? Is it warmed up when this happens? How often does it happen?

Do you see this "loss" in the RPMs or speed?

Did you check for grammer? There is such a thing as periods (.). I cant even read what you wrote, it all just blends together.
