91 454 wants to stall when you goose it

my 91 Suburban 454 started to stall when I give it gas, it will idle fine and run 90 if I accelerate normally, but if I punch it it seems to stall and cannot jump into passing gear while doing 50, it wants to stall if I give it lots of gas.

No black smoke out the back everything else is normal
