2015 Dodge Journey fuel system problems

I have had my car right at 3 months and it just shuts off with no warning. I have children in this car going down the interstate and it just shuts off. There is no warning signs and no way to get it off the side of the road. I'm just dead in the water hoping no one will rear end us. It has been in the shop 2 times and they have it a day and say shows nothing and send it back to me. It is very hard to get it into the shop and they act like I'm the problem cause they can't find it.

This occurred in a driveway upon start-up of vehicle. The vehicle refused to start during cranking of engine. Dealership was contacted for advice, they recommended to jump the vehicle. Directions were followed with hood in the open position and fuel was observed spraying out of the engine compartment upon cranking of the engine. The dealership was contacted again in which they towed the car to their shop to diagnose the problem.
