94 dodge shadow stalling when shifting gears and reverse and drive

What is your question?

car starts fine, fire up every time, i let it run for 10 to 15 minutes, its been 10 degrees all week. yesterday i put it in reverse to back out and before i can even get to drive it stalls. fire it right back up with a pump of the gas, put it in drive pull back in put it in park it stalls. it always starts up and seems to idle fine in park and neutral. what should i replace or try to check out.
