Car loses power in the mists of driving and once you floor it, it smooths back out and does it all over again sometimes in a matter of seconds. all the basic parts; plugs, wires, cap, rotor button, air and fuel filter have all been replaced

Sounds like your sensors are responding to the situation/condition and trying to adjust and correct. I would suggest a cleaning or replacement of injectors, would try cleaning first, and I don't mean a fuel additive, I mean removal and wire cleaning in individual orifaces, as well as a blasting.
