Question about 1989 Oldsmobile Cutlass Ciera
Fuel injection seems to cut off

Do this before you do anything else. On the 3300 (3.3L) engine, there is a common ground post beneath the air cleaner, under the crossover pipe, on the transaxle housing. It loses contact on these older models. It is among other things, the ground for the ECM, and will stop the car cold. Take the four terminations, which ground a total of 8 wires, loose. Clean it all up, and buff the terminations with some sandpaper to get any corrosion off. Be sure when you're loosening and tightening the nut to use a backup wrench on the hex base of the post itself, or you'll behead the terminations of the ground wires. Snug it all down and you'll be back in business. Be sure to disconnect the battery before doing all this because you don't want to buy a new ECM.
Yes, it's hard to get to. It's no fun doing this. But it is what usually causes this problem in these old 3300's. I blew over $2000 replacing stuff before I figured it out.

No it wont cause the charge light to come on but the engine check light. The problem your describing especially with the charge light Suggest electrical issue, and with the stalling it points to the alternator. try the following
1.) tighten both battery terminals and ensure the battery is secure.
2.) check alternator charging voltage with and without loads (ac and headlights)
voltage should be 13.5 to 14.2 above that is bad as well as below that.
3.) check the tension of the alternator belt and tighten or replace. (most likely in your case)
Verify the above 1 of them is your problem.
