Default 1989 Mustang shuts off at idle Help!!!

Some months ago I posted a question regarding this and recieved some very helpful advice. I am hoping for some more problem solving.
Some background: The car was running fine until one day I took the car to 40 mph in 1st gear , then 60 in 2nd gear.. Right after that the car would cut off when I would let off the gas..exiting the highway ect.

I have changed the MAS air flow, the MAP , the throttle position sensor. No difference.

I just put a new 331 engine in, and the problem still exsists.

If you need the specs on the engine I can provide them .

Any help at all that will get this car running will be greatly appreciated.

Thanks in advance
