Update.
Drove to work, about 10 miles and mostly highway. It seems like it happens much more when I go from 55+ and let it coast before downshifting that it dies. It happened each time when I was above 55 be it coming to an on ramp, getting off, etc. I was lucky enough to watch it and not wreck the damn thing.

Aftermarket TB's have been known to cause more problems than they cure. They certainly don't add any power unless you're heavily modded or running a strong FI since the stock TB can handle more air than even mildly modded 4.6's need. Whatever you do, hold on to that stock TB.

Yup.
You're assuming I went aftermarket. I ordered a ford stock replacement.
I did take the TB off yet again and cleaned it even more and the symptoms are not AS bad, but I do believe this is because the TB electronics are on their way out.
