This sounds like a fuel pump issue. I would suggest hooking up a fuel pressure gauge and taping it to the windshield so you can monitor the pressure when this happens. I suspect the pressure will begin to drop and then it will cut off. Also, when trying to restart you should have proper fuel pressure. If you can get it started with starter fluid that will help prove this out but here is all the testing needed to determine this is the cause. Once we can rule this out we can move on.
