Ok this was all after the car was all warmed up how far can you go from a cold start until it "dies:?
I want to suspect a crank sensor or ignition module just because of the symptoms if nothing happens until the egine gets hot ,typical of a failing crank sensor andignition module, always replace them togother.
But there is one more culprit, the catalytic Converter, see they break up inside and over time the catalyist bounces around and becomes a ball, on acceleration the presssure of the exhaust pushes the "ball' of caytlist into the exhaust pipe opening restricting it until it shuts off the car. You pull over the pressure goes away the "ball" falls back into the cat, you start again and it starts all over again. I would hve the cat tested and you can do a test yourself hit the cat on the bottom with a hammer and if you hear some rattling inside when you hit it yhe catalist is broken and is likely your problem.

The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

this could be one of the two things that I am thinking it is...it is either the throttle position sensor or it si the fuel pump getting too hot and cooling off slightly enough to restart the engine. Both are related but separate systems. The throttle position sensor is on the side of the throttle body and it merely tells the computer where the throttle plate is in the throttle body to create the proper fuel mixture for the injectors. The fule pump ios loccated insid eof the fuel tank it either runs or it doesnt usually. If it gets hot it is about to go completely out all together.

1- check there is spark come from spark wires
2- check the fire timing by looking for every wire in the right place
3- check there is injector signl
4- check for any vacuom leak
5- try to clean the MAF by brake and parts cleaner
6- try to reset all the code and see what will come after that

I know you mentioned the EGR valve has been replaced, but you may have a bad 'new' part. I know the car is electronic, but has anyone checked its ignition timing (timing belt been looked at, I know it only has 77k on it). Is the fuel pressure regulator OK and it vacumm supply?
