It sounds like it is starving for fuel when you reach those speeds.I believe it to be the fuel float in the carburetor.A new carburetor is very expensive as with a rebuilt unit.If you are mechanically inclined you can replace the fuel float and needle valve for about $20 or get a complete rebuild kit for about $35 to $40 dollars.If you have ever built a plastic model you should be able to do a rebuild yourself.A good quality kit comes with complete disassembly and assembly instructions with diagrams.Give it a try.

SOURCE: How to change fuel filter on 1996 Ford Bronco, 5.8 l engine

You'll need to have a fuel line disconnect tool. This tool can be made of plastic or metal, but the utilization is the same. You can purchase these tools at most auto parts stores. The fuel lines have a "quick disconnect" end on them where the filter attaches. After you've relieved the pressure from the fuel line (line pressure's usually around 60psi so you should wear eye protection). Techniques vary you can remove the fuel pump relay, and start the engine till it shuts down, or (needs another special tool). Attach hose from tool to test port on fuel rail by injectors and drain fuel into suitable container. You can also remove the cap from the test port and with a rag covering the port to catch fuel, depress the schrader vale (like a tire valve). This isn't really the best way,because gasoline can get on you and will inevitably get on the engine. Not always a good situation if engines hot. (To be honest with you, at work I usually just slightly disconnect the line at the filter. Only enough to bleed the fuel pressure off and let it drain into a bucket.) To remove, you'll have to insert the tool into the line around the filter neck at one end. You'll then be able to separate it from the filter. Repeat on other end. You may have to wiggle and twist a bit, as the filter necks might be sticking to the o-ring seal in the connector. Don't force it, as you can damage the connection, and you'll then be purchasing new fuel lines. Most of these filters are retained in a bracket on the frame rail using a big hose clamp. Naturally you'll have to loosen that to pry out and remove the filter. Aside from the initial fuel spillage, and any fuel that might drain down through the lines, the fuel in the tank will remain in the tank. Typically the filter is mounted well above the tank where the pickup tube is located, so siphoning won't be an issue.
I hope this helps

SOURCE: 1994 ford ranger extended cab 6 cyl fuel injected 2 wheel drive automatic

This year of ranger had a few flaws, In one case, a break power booster was robbing the vacumm, you can test this by plugging it off and seeing the differance, but you will have limited brakes. This model year had a problem with a vacuum leak on the manifold. You can check these in many ways, but please don't use starting fluid. The rear of the manifold usually on the drivers side where it seals to the block.
Also, in 2 other cases a cracked head has gave me the same problem. It is caused from a loss of vacuum.

Timing is everything. Try testing you PCM. It's the little gray box near the base of your distributor. If you have spark, and fuel at the rail (plus good fuel rail pressure) than the timing is your problem.

Check the pet-**** on the fuel rail assembly to make sure the fuel at the rail is under presure and getting to your injectors. Then again make sure you have spark, lastly you should be able to test the trouble codes to see if your PCM is the issue.
Goos luck.

You may have dirty or clogged fuel injectors, may also be problems with the ignition system. Might also check the fuel pressure to make sure the fuel pump is working correctly.

Check for timing gear problems. They have plastic teeth on the cam shaft gear which will shatter causing it to jump time.
