Need help ASAP! stalled twice already

my 2004 f150 fx4 5.4 triton started a knock, then within a week or two it kept getting progressively worse, especially when accelerating, eventually once the tuck was warmed up and would begin to decelerate it stalled, it will still start and run but i have not driven it since, what could be the issue?

Find the source of the knocking, and you will correct the dying and stalling. There are 2 knock sensors in the valley of the engine that will change timing enough to make it stall. Rod bearings, main bearings, cracked flywheel, etc. Way too many choices that can cause a knocking sound.
