I had to change fuel pump in November and now truck had been running fine now the truck has stalled as i hit the breaks and will not restart

When you changed the fuel pump did you change the fuel filter? I changed mine in my expedition 3 months ago and also changed the filter. Reason to change is because a fuel pump usually fails because of a semi clogged filter. The pump has to pump a lot harder thus it burns out. First i would check to see if pump is running. Have someone turn the key on and listen with the gas cap off. If you hear the pump engage then it may be a clogged filter. If you dont hear the pump then it maybe your pump reset. My pump reset is located on the passenger side front seat just in front of the door. Plastic shield must be taken off. There is a red button that you need to depress to re engage the pump circuit. Once you depress then it should start. Check your manual for pump reset location. Good luck
