Exclamation Electrical Trouble

Hey guys, it's me again, i wanted to ask of my car, it's giving me problems with the engine, it suddently shuts down when Im driving but just at high speeds (around 75, 100 MPH) and after a while, but it looks like it's something electrical because my dealer already changed my MAF sensor, the engine switch, the coils, the sparkplugs, the fuel bomb, and alot of things and it stills turning off, recently i was driving back to home and I decided to take the car at 90 MPH to see if they still had the problem and after 1 mile, it shut down again, i called the dealer to claim the warranty in the car service and they come with the diagnostical computer to see what was happening to my car and it indicated that my MAF sensor was the failure but it was new, so, we tryed to turn on the car again but it didn't want, they checked the gas pressure and it also was ok, and finally the person who was scanning the car decided to reset the computer and the car finally started up, then, they told me that The computer could be the problem and they want to replace it for one new but I don't really know if it will really solve my trouble because they have changed a lot of parts of my car and i spent more than 4,000USD in services and the problem remains, i know the computer is not cheap but i want to know if all of you that are experts and love your cars, think that changing the computer would be the solution.

I really hope you know about this cuz' now im really giving up, thanks to all for the time to read this and post an answer. sorry if my english is bad. see u soon!
i have the 2000 3.8 impala.

Can you please post the diagnostic codes that they are reading? We can't really do much except speculate unless we get those codes.
