All fluids have been checked and fine. No service engine or check engine light on. It will start, but when put into any gear will die.
Bummer deal! You have a dirty idle speed adjuster which means , being dirty, it is cutting off the air supply and stalling. Above idle speed, air comes from the throttle plate opening and everything is OK. Sometimes, sticky valves will cause the same problem. Here is where you get the right cleaners for both and end the stall problem. http://www.auto-tune-up-and-repair-options.com/Engine-tune-up.html
It can be low fuel pressure issue or clogged fuel pump. Or its engine related issues,--------------- Engine stalls, car stalls while
starting, vehicle stalls while starting, Engine stalls and dies, Car stalls and
stops,

Sounds to me like a fuel related problem. When heavy accelerating more fuel is pushed through the system. I would check the fuel filter, and its possible its the fuel pump, but usually once the pump starts acting up, within a few days it will go out all together.

Check the Fuel injection system (injectors) and the intake manifold. It might also be wise to check the alternator as well as the starter coil and also the electronic distributor

I have the same car and had the same problem with the engine wanting to stall out, I ran fuel injector cleaner through it and also an octane booster, i also changed out my plugs and wires and belts because i was also having the occasional squealing sound after i did all of that all of the problems have stopped and now my car runs like a champ

fuse or wire harness, checked the voltage present in the fittings? Switch on before checking.
you get 12 volts more or less?

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.
Engine stalling and rough run
issue at low speeds
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
