2019 Ford F-150 fuel system problems

Noticed during summer 2020 months the truck when idling at stop would vibrate and tachometer would bounce. Recently during july to september the truck when stopped would idle rough then shut down completely having to put in park and restart the truck! The last time it did it I was sitting at a red light on a city street and it just shut down and I had to restart the truck. This has happened 4 times since july. I took it to two ford dealers and neither could replicate the problem and told me they could not fix it.

The contact owns a 2019 Ford F-150. The contact stated while driving at an undisclosed speed, he heard an abnormal sound and observed smoke coming from the engine compartment. The vehicle then inadvertently lost motive power. After a visual inspection, the contact observed that the high-pressure fuel line was disconnected. No warning lights were illuminated. The vehicle was towed to the dealer, who diagnosed a failure with the high-pressure fuel pump. The vehicle was not repaired.
