2005f150 5.4 stalling?
Have no idea what is causing truck to stall out. 70,000 miles, regular maintaince. Truck has been stalling just feels like it is reving down and then slowly stalls. Has happened under accelration, when coasting and at a stop. Does this sound like a fuel pump or filter issue? Truck runs strong otherwise

there's only a million things that can cause stalling; have you cleaned your maf meter as part of your 'regular maintenance'? If not, I would start there, even if it's not related to the stalling; its the single most important sensor for the pcm. As for the fuel pump, you can track the delta fuel pressure and fuel pump duty cycle on a good OBDII scanner to get a better glimpse of what is going on, instead of guessing.
