Still sounds like a fuel problem. Try a full tank of supreme gas, plus put a can of SEAFOAM into the tank to help clean you injectors. See if this will help clear up your problem. Did you change the plugwires????

Known GTP problem.
You most likely have a bad fuel pump resistor, which controls 2 speeds of the fuel pump.
To check to see if this is the problem, there is a trick you can do and its very easy to do. Go to the attached link, and bend the tab my finger is pointing at and then plug it back in. If your car starts and runs fine, well we just solved the problem.
