Fuel rail sensor
My 2004 f150 f×4 is riding real rough from 30mph to about 45mph and sometimes after stopping at stop sign or make quick stop it tries to kill like it's out of gas I had fuel rail sensor code when plugged in truck 2weeks ago and saturday it only had o2 sensor so i changed o2 and still doing it could it be fuel rail even if it's not showing an error code ??? Thanks for help I'm new to forum and it's been alot of help

The very first thing to do is inspect your fpdm on rear axle . fuel pump demand module very - very common failure. Corrosion thru back due to aluminum mounted to steel eats a hole then water gets to circuit card , gets really confusing symptoms . Look at stickys at the beginning of forum . If that's okay we will move on to other stuff .
Codes are not all that ,its like when your sick the doctor adds up the symptoms and does tests . Some are caused by the illness others maybe directly tied to the sickness .
Low oil pressure always shows up when engine shuts down but its not the cause of the shutdown .
