You said you checked the spark, I assume it had spark, So I will go from there, If it had been running and stalled but still appears to have all the required things to run (compression,fire,air,fuel) then it must be getting ONE of them at the wrong time, sinse fuel will hang around for A while and air will have to be there for compression, Then that prety much leaves only one thing, The fire, I would guess that your car has jumped time on the timing chain/belt,,,,, NOTE, A v-8 (or more) engine will run when it is out of time by one tooth, But, most 6 cylinder or less engines have great difficulty hitting at all when they are out of time on the cam/crank,,,,, This is due to the increased separation between cylinders, The lower number of cylinders you have the more separation. , Jamison.,,,,,,,,,,,,,, Keep in mind that there could be other problems with the car, It is very difficult to say why an engine is not starting, especially when you have never seen or heard it.

As strange as it may sound, If your battery is old and getting weak, it can cause that stalling problem with the Dakotas. Your IAC may also need to be cleaned/replaced. Good luck ........

If your Pontiac runs a 700r4 gm transmission you have stripped a reverse input shell. The transmission needs to come out for repair.
