So when you say you have replaced the ENTIRE fuel system you have replaced: Gas tank, Fuel sending unit, Fuel sock, fuel pump, Fuel lines from tank all the way to the fuel rail, fuel filter, fuel rail, fuel regulator, fuel injectors, fuel return line, and filler tube to the tank? That’s a lot of stuff to replace on an 88 Buick. Probably cost more money then the car is worth. I would look at the possibility of a sensor that is over heating and killing the car. Or a bad computer. Have you had the repair shop do drivability on the car? If they have not or if they are not equipped to do a drivability on the car then you need to take it too the dealer and have them do it. There is something that is happening while the car is in motion that the computer is not recording or is seeing it as a no problem situation. Drivability test will allow them to see what the computer is seeing the whole time is it being driven. They can record up to 4 hours with this test and view the results at the shop. This is what I would recommend with an intermittent problem like this. Contact your dealer.

Have you dropped the tank to see what condition the top of the tank is in? Had a truck that would idle even at a couple grand of RPM that would stall at highway speeds. Ran that through a diagnostics too, that showed nothing wrong. I tracked the fuel system back to the tank. Turned out to be a hole in the top of the tank. Replaced it with a junkyard special, with fuel pump and it ran fine afterwards. Funny thing was I only dropped the tank to see what shape the wiring to the fuel pump was in. The only thing I think may have been going on there was the pump volumn was sucking air or moisture through the gas when it got down to a certain level.
If you decide to go through the hassle of dropping the tank yourself, empty the tank first. Disconnect your battery, then disconnect the fuel lines and wiring. Support the tank with jacks. It is heavier than it seems. Should be from two to four bolts that strap it in.

I had a Geo Tracker that would do that and my brother did a diagnostic on it, couldn't find anything... Turned out to be a MAP sensor and one other sensor that I cannot remember... I guess try that and see if it works...

properly 2 motives for stalling in all autos. defective ignition gadget, or gasoline starvation. i might verify the basics: spark plugs, gasoline pump, gasoline line, gasoline filter out, ignition coils, ignition wires, gasoline injectors (or purely get some injector cleanser). If that isn't the case then it ought to have some thing to do with the ecu, i might propose going to a mechanic for that vehicle computers are quite complicated.

It can be the module in the distributor, they go bad and the diagnostic's don't show it.
