Are you loosing spark to the plugs or fuel to the injectors when the engine stops ? You have to know which system to troubleshoot the problem.
New fuel injections it don't have a spark to the plugs when the engine stops
Ok, well thats the system you need to check out. You may need a repair book to get the flow charts for the ignition system including wiring diagrams.
You did not mention the ignition control module the coils connect to. Did you have it tested or try a used module ?
And are there any trouble codes stored in the computer ?

try messing with the radiator because it is most likely overheating

dont look for air when the car cuts out its most likley spark or fuel when it cuts out ranomly its usually a sensor or relay that is faulty check fuel pump relay and camshaft or crankshaft sensors but first narrow it down to spark or fuel if possible also if check engine lite is on check codes

Very easy for the Mass Air Flow Sensor....it is in the duct between the throttle body and the air filter box. Just unclamp the tube and remove the old and replace with the new.
On your pack....I need the engine size.

Just hearing the pump alone is not enough. You may be right and the fuel system could be fine. But you have to know what the line pressure is on fuel injected engines.
When the tune-up was done was the air and fuel filter changed. Sometimes people get a tune-up but the filters were not done or included in the service.
I would guess that it has to do with the fuel system.
Did the engine light come on and if so were any codes stored and/or retrieved?

Check the Idle accelerator valve located on front side of throttle body, it is either stuck or needs cleaning real bad, this is what controls your idle speed, by letting small amount of air in. It has a plunger on it that moves back and forth slowly to adjust amount of air mixture, it is controlled by computer. Unplug it and just turn on key and check for voltage.This valve gets real gummed up, probably need to take apart throttle body and clean. HUNT
