2004 Taurus 3.0 Vulcan Ehgine noise Houdini act

My 04 Taurus has a distinct engine knock that persists until car warms up, then.......poof. Nothing. No tick, knock, squeal. Nothing! It’s frustrating me to no end. Any ideas? Engine oil is and has been full. I use mid grade gas and drive 100-140 miles a week in general.

You say "mid-grade gas"? As in "higher than 87 octane"? There's your problem; your car is running on gas it isn't meant to be using. Once the cylinder heads warm up, it may seem fine, but you're building gunk on your spark plugs and injectors running higher octane fuels.
I suggest pulling out and checking your spark plugs and fuel injectors, and if they seem alright, switch to 87 octane fuel and go from there.
