1990 RX-7 GXL Dying After I Let off the Throttle

My 1990 RX-7 GXL idles fine, but after I rev the car up it starts to die. We've replaced the fuel pump, fuel filter, and cleaned off all of the grounds. Here's a video of the problem: https://youtube/TRo3oeffTpA
I was wondering if any of you have an idea of what the issue is. Thanks in advance.

Have you tested the compression? Also test/adjust the TPS with multimeter. Look for any loose vacuum hoses or leaks. Check the AFM, make sure it is connected and not stuck shut.
