Ok so for some god for saken reason all of a sudden my cars is starting to act up. My car will shut off if i am under heavy breaking. It has done it 3x times to me this weekend. The only remedy that I have found is to jack up the front end it will suddenly get pressure. I know the fuel pump is working since it will give pressure to the rail and the pump is only 6months old. I dont think its bad fuel cause its only on hard breaking not regular breaking. I read somewhere about fuel leveler or something having to do with the fuel pick up and allowing it to get fuel from the sump. Fuel level is at 1/2 a tank so I know I have gas. I didnt hit any major pot holes and I dont see any dents on the outside of the tank. Any quidance would be great guys thanks..

I'd run the car until the gas was nearly gone, drop the tank and check the baffling inside the tank.
