2013 Volvo S60 Fuel System Problems

I had a 2008 volvo s60 and now i have a 2013 volvo s60. And the same exact thing happened with both of them. Both cars had more than half a tank of gas and while driving on the freeway they started to stutter and then the car just shut off while i was driving. I was lucky to be close to an exit and i had to let the car role on nuetral till i was safe away from any traffic. If i want close to an exit you can just imagine what would of happened. When i tried to turn the car on it wouldn't start anymore. I have done knowledge on working on cars and new it was a fuel problem. Upon checking i noticed that the fuel rail didn't have any fuel pressure. On my 2008 the problem was the fuel pump module. On my 2013 its a newer car so i don't really know much about it. Only had it for 2 weeks. And now it got towed and is at the dealer where i bought it from to get checked by their mechanic. There must be a problem with s60's to have happened to both s60's I've owend.
