1984 toyota stalling

My 1984 toyota pickup 4wd with the cabureted 22r 4 cylinder engine will start, run, and idle fine. The problem is that when the engine reaches a certain load threshold it stalls. This happens while on the road at speeds that vary depending on conditions, but usually around 45-60 MPH. In order to fix this issue I have replaced the fuel pump, the fuel filter, all vacuum hoses, the carburetor, the radiator, the ignition control module, the catalytic converter, the ignition coil, and the power steering pump. I have tested the pressure on the EGR valve and the EGR vacuum modulator, tested the distributor diaphragm, and performed a complete tune-up including new plugs, wires, distributor cap, rotor and timing.
I am at a loss as to why this vehicle would still be stalling while driving when it reaches a certain load threshold, and have no idea where to go from here.

Does it sputter, backfire, bog out, or just shut off when the problem shows up? Does it restart right after it stalls?

Nothing signals the stall, I am driving down the road and the engine just dies. Since the engine is running and it is in gear, it starts right back up when I let off the foot-feed. Sometimes if I do not have the accelerator pressed down enough the vehicle bucks while it is stalling and restarting, but releasing the foot-feed solves that problem and it starts.

I believe there is a sight glass on the carb to view the level of fuel in the carb bowl. Next time it stalls, instantly turn off the ignition (not to the steering lock position) and push in the clutch so the engine doesn't spin. Then look at the level of the fuel in the bowl through the glass and see if it is at the right level.
