2016 gt fuel pump code, 4th fuel pump

We are on our 4th fuel pump in 10 days. Car quit and was giving a fuel pump code. Put new pump in and it started right up. Drove it home 30 miles and car wouldn’t start the next day. Read fuel pump code again, thought we bought bad pump. Did this 2 more times. Car started every time and only lasted for 1 time driving. Took car to shop and they said we needed motor craft pump so they put it in. Car got me home. That’s it. Car hasn’t started in days. I put car back to stock tune (had a Bama plug and play tune) car started right up. Drove it for about 15 minutes. Parked it. Waited a few hours, car started right up then stalled out after sitting idle for less than 2 minutes. Help! I have never used forum before.
