Fresh LS Volvo

So I just got this car on the road , it's a 1984 volvo 242 that I stuffed a 2004 Ls1/t56 from a GTO into.
the car pulls really hard for maybe 30 minutes of driving but after awhile once I push the pedal more than 3/4 throttle it will start to spit and not pull anymore , it' almost feels like a fueling issue but its intermittent so I dont think that's it . I unplugged the o2's and drove it for awhile and same deal pulled hard for awhile but eventually it wont accept a heavy load. If idles great and is responsive. Any thoughts ?

Sounds like a hose getting sucked flat after it gets very warm.
