Does it have a carburetor or fuel injection? If a carb and you give it throttle real slow does it still die? If not look at the accelerator pump in the carb.
Another possibility is the catalytic converter may be plugged. Easy check is get a vacuum gauge. and "T" it in to a vacuum line n the engine that pulls vacuum whenever the engine is running. slowly throttle up, and if the gauge jumps up then slowly drops off to nothing at the same time the engine slows down and dies .the engine is choked and you have a restriction in the exhaust
Have you checked the ignition system out? Sometimes bad ignition components can cause this problem. Change the spark plugs, wires, distributor cap, and rotary button. Also, check the carburetor's acceleration pump for operation. With the engine off, remove the air cleaner and look down the carburetor barrel. Quickly move the throttle lever from closed to fully open (or have a helper quickly push the accelerator pedal to the floor a few times). If the acceleration pump is working, you should see a stream of gas spray into the carburetor barrel.
Lets also not forget to check the fuel filter for clogs, and or dirty fuel, rule of thumb is to replace the fuel filter at 30-40,000 mile intervals, also is this vehicle carbureted or fuel injected, if injected its possible you have a bad fuel pressure relief valve problem(low rail pressure to the injectors) follow manufacturers repair/diagnostic procedures. Also if this happens only after the car is driven and warmed up a while, it is possible to have a clogged catalytic converter, consult a certified tech for testing procedures if you are not familiar with this diagnostic procedure.
Be certain you have a good gas cap on the tank as a poor /clogged gas cap vent can sometimes cause stalling on acceleration.
Could be, plugged up fuel filter, incorrect fuel pressure, failing fuel pump.
Your engine probably has a vacuum leak
No gas in the engine

There can be several causes that the engine will die when you press on the break of your 1994 Chevrolet Caprice. The most prevalent cause is restricted fuel flow. The engine can get enough gas to run when the accelerator is depressed but not enough fuel when you apply the brake.
Key on, engine off, press the gas pedal to the floor three times.Key on, engine off, press the gas pedal to the floor three times.
the engine timing needs to be adjusted
Key on, engine off. press gas pedal to the floor three times.Key on, engine off. press gas pedal to the floor three times.
TOO LOW OF OCTANE.TRY 89 IF STILL RATTLES GO TO 91 OR 93 OCTANE. U WILL DAMAGE YOUR ENGINE WITH TOO LOW OCTANE.
Turn the key on, engine off, press the gas pedal to the floor three times.Turn the key on, engine off, press the gas pedal to the floor three times.
Most of the time ,it's because engine is catching air .check for a hissing noise. a soapy solution in a spray bottle .while engine is running will find where the leak is .engine sound will change when you find the spot .
