Does it pull down like your stalling a standard or is it act like no fuel?

Sounds like CAM sensor or possibly TC but usually if they are going it will do that in reverse

I'd try the cam sensor first, but it sounds like the converter may not be unlocking.

I'd still try another cps. If you got one at a parts store they are known to be less reliable, may last a day, maybe a year, luck of the draw. Easy check. Need a spare anyway. Get one from ford or ih, better but still can quit.
