no sputtering or rough idle it just dies at that point i roll to the shoulder and restart with no problem. I have had two mechanics try and solve the issue with no success. They did a tune up and cleaned the fuel injectors and replaced the fuel pump and the mass airflow sensor.

Yep, those the popular items and services to do when this happens. Did they run the codes to see if any were stored?

But I have seen more than a few times that it is the crankshaft sensor that goes bad and will not leave a code. Here is the location which is under the starter motor on the right side of the engine so you can check it out. Make sure to disconnect the battery first and let me know if any codes come up. Check out the images (below). Let us know how it goes

Intermittent stalling is one of the hardest problems to fix because it can be so many different things. The crankshaft sensor or bad MAF sensor can cause this issue. Have you run the codes yet? If not please go over this video
