I have a 2006 f150 5.4 lariat. I had my engine light come on a few months ago after my truck almost died, it was a misfire cylinder 7. I had just replaced all plugs so I replaced coil pack on 7. Truck ran good for about a month. Light came on again and ran crappy, kept loosing power like it wasn't getting fuel. Code was for fuel pressure sensor. I replaced fpdm, filter, fuel rail pressure sensor. Seemed to be fine after that chunk of change. Then of course it happened again, same code and same symptoms. Now it's terrible, it almost buckles instantly when I accelerate then I have to baby it till it gets enough power to go. Any ideas?

Fuel pump?
Seems like the only thing left to change on the fuel supply side.
I have the same year Lariat as well. How many miles?
I hope I don't have to tackle the fuel pump anytime soon.

I bought it with 107,000 and it all started around 115,00, have 120,000 now. I thought about fuel pump but that's way to expensive to not be it lol. And if it was pump wouldn't it completely go out not just randomly at times? It's usually if I drive a long distance or when's it really hot out.
