1997 Mercury Cougar xr7 with the 4.6

Hi I’m having this problem where my car had a dead spot in the throttle. No matter if it’s in park or drive or whatever, it runs perfectly fun before and after about a 1/4 throttle but when you hit that spot it just cuts out but passes it and is fine. It’s not intermittent it does it every time no matter what. I will give further info if needed but I just can’t figure it ou, any help would be appreciated thank you
