Car died, now won't start

I fueled up with Supreme Unleaded, drove approx 25 mi on freeway, drove to my friend's house and not 400ft away, my car power killed and the motor sputtered, but didn't die until about a minute after this all went down. Started it again, no power and when I pressed down a little bit on the gas pedal, the motor killed. Previous owner replaced fuel filter and pump, I've had the car for 4 months with no issue until now. *The front side to mount is broken, not sure if that counts here*
