mine does same thing exactly!! does okay when i get moving,but much worse if i have a full tank of gas,so i just have to put less in more often,mine sometimes just kinda surges off on its own,and i have too hold the brake too stop it,it does it a few seconds every now and again,almost as if my throttle is sticking,but dont think that is it.I am leaning towards some sort of vacuum problem,i so hope it is that and bad tran.maybe that is your problem too,maybe it pressure checked for leaks.
