Answer
Yes, I do remember your car. The main things that cause your problem are the crank sensor, ignition module, coils, and the ECM and you said you tried them all.It could also be a fuel pump binding. What needs to be done is the tech needs to let the car run until it dies and then check it right away to see if it is loosing spark or fuel or both. Then go from there. I have also had the wiring harness from the crank sensor to the module fail due to heat because it was soaked with oil leaking from the intake gaskets.
