Anyway I had something similar not too long ago..
Was driving me crazy..
Long story short, it was the Fuel Pump (or could be the regulator) for me.
i was kinda having the issue prior to me replacing the fuel pump..but it gets worse after replacing it..but apparently i didn't install it properly.
I just replaced the whole fuel pump assembly with a new pump. I took the opportunity to upgrade the pump.
Car will start fine and then stall after a while out of no where , it starts right back up ..
But then gradually get worse in which i have to wait like 5 to 20 minutes before it starts again.
The longer it goes the shorter it stays on and the longer the cranking.
You can easily test the fuel pressure by getting a fuel pressure/vacuum tester, unplug one of the Low pressure fuel line (preferrable the one closer to oil filter, plug in to the fuel pressure test.. Put the car into ON position without starting the car. You should see the pressure build up and stay at least or above 35 to 40 psi ( i think can't remember).
keep it that way for like 5 minutes or so to make sure the pressure isn't dropping..
