my car runs fine when its cold. when it gets up to operating temp it starts to flutter then die then it wont start for about 1 hour then will run fine till it gets hot again. i replaced the egr valve the coil packs and the icm,and fuel filter and i still have the same problem. i took in to a shop and hooked it up to a computer and flashed no codes and tested the fuel pressure from the fuel rail and tested good, but told me the EGR valve was electronicly unplugged. they plugged it in and seemed to run fine. so i left and two blockes down the road it flutters and dies while im driving. it doesnt matter if im driving or im parked it does the same thing

If they tested the fuel pressure and it tests ok
Test the Injectors.
They may being shutting down the Quad drivers in the ECM (computer)
If this is the case,i would replace all 6 injectors and the ECM.

Another thing to check; Check for spark when it dies. Crank sensors and control modules were common failures on these engines. Either can be heat related, and neither will always set a trouble code.

If you can get your hands on a scanner, look for cranking rpm. And, a noid light to check for injector pulse. I'd suspect the crank sensor, first, but still could be a control module. Hopefully, I'm wrong on the module. They are quite expensive.
