I have a 13 f150 5.0 with 200k miles the new engine has about 23k on it. For the last month it has been intermittently stalling while at an idle or coming to a stop. I took it to the dealer no codes they said they have no idea. I have re wired the 27 fuse for the fuel pump per the TSB, replaced the fuel pump relay module, cleaned the MAS and replaced the air filter. All of my sensor readings seem to be in normal
ranges when scanning live data with one reader. Including fuel pressure. I have read about the possibility of it being the torque converter but transmission shop tells me it would feel more like popping a clutch which it does not. Runs smooth and then just dies. The only other thing I can think of is the fuel pump. Any insights would be appreciated.

 

I have a suspicion of what may be going on, but could you please post the data that your scan tool has given, thanks?

 

Thanks, I haven’t had a chance to hook it up again so I can get you a screen shot I will try this afternoon.
