Engine dies when I step on the gas

Thanks AJ for your insight. I tried to go up the hill with the engine (relatively) cold today because the car has never stalled when it was warmed up, only when cold. And the choke seems to work as it should, shut when cold and fully open when warm.
It very well could be some problem with the ignition system, it appears to be all original to the car, but my question is why would it only stall in "Drive"? when its in "Park" and I rev the engine, she revs up just fine without a hiccup.
Thank you for the info though, it will take some time for my noob brain to take it all in...
