Fuel Hoses Lines/piping And Fittings problems of the 2008 Hyundai Elantra

Engine cut off with fuel gauge dropping to 'empty' [ with a 1/2 full tank]. On the nys thruway almost causing a collision with an 18 wheeler as I coasted across its path to the shoulder in rockland county. Called aaa and eventually, [about 10 min. After, while still on the line with aaa, I heard a light click and the fuel gauge went back up to 1/2 tank and the car engine started up to complete my drive home.

I have a 2008 Elantra that continues to stall and hesitate. This occurred on two separate occasions and I was almost hit from behind. The dealership has failed twice to diagnosis the problem and I have filed a complaint with Hyundai. Now they want me to take the car back to the dealership and leave it overnight. They don't currently have a loaner car. My car was not a part of the recall, why? I don't know. Clearly there is something wrong with the fuel line and I am afraid I am going to hurt in a car accident.
