Sounds like fuel slosh. Ever happen on a full tank? or always with lower gas amounts?

even on full tank it happens

Im thinking you may just need to do a tune up. I am guessing new plugs (NGK only) and wires will fix the problem, but if its been a while i would also replace (or clean) the air filter and replace the fuel filter.

check your grounding, especially to the fuel pump... you may have something loose, and under hard lateral acceleration it breaks contact for a split-second. do the other electronics seem to falter (clock resetting, lights flickering, radio shutting off or skipping a beat etc)?

no radio and every thing playsfine put new plugs ,and filters less then 8k might need new wires but they look fine. i think its more a ground problem ill check it out in a few weeks when i pull my engine it might be a little easier

Well, grounds are an easy fix, buy a cheap ground kit or make your own for like $15-$20. They sell 40ft of fugly blue 8 guage wire at walmart for like $10 or something and all you have to do is find some extra little crimp on pieces for the ends.
