These engines are known for the water pumps and/or the timing chains hydraulic tensioner failing and causing the timing to jump time. And checking the timing on these engine is not easy unless you can get a scan tool that can tell you if the cam and crank are in sync. If it says out of sync it has most likely jump time.

SOURCE: quits while driving replaced many suspected parts

try this, the next time it quits leave the key in on position and get a broom stick and go to the passenger side of the car. About straight in at the back of the door ,reach under with the broom stick and tap the plastic gas tank a few times, have someone try to start it or go start it yourself. Mine did this even after the garage checked it out and cleaned the tank. Come to find out dirt settles around the fuel pump and clogs it. They just blame the pump but in my case the pump was fine. I was told Alero used a very small fine mesh in the sock that goes in the fuel pump and they clog up. But most of the dirt was around the plastic guard around the fuel pump. See if this works and let us know. Good luck

WOW a 94 with 46K on it thats rare. Your computer may be bad it sends the pulse to the injector.

SOURCE: Vehicle dies while driving down the road.

could it be the A/C pump kicking in. might be boging down the motor or electrical circuit, not letting the injectors get enough power. This could happen if the bearings are going bad in th A/C pump or there is a short in it. Just an idea. sounds like you have done the main components.
