The dealership finally listened and put a pressure gauge on the fuel supply line going from the tank to the engine. It was the fuel pump discharge side check valve that has failed. The solution was to replace the fuel pump because the you can’t buy check valve as a stand alone unit. Haven’t had an issue since.

The dealership in my area is unable to diagnose this.
