Nasty Hesitation than Stalling..

Hey guys. Today I took my Dart for some Christmas shopping. Drove about 30 or so miles on the highway at about 60MPH. Noticed a slight hesitation the other week after pulling out of the gas station. Car ran great on the highway all today. Finally after about a 40 minute cool down started to get a really bad hesitation from a stop. Let off the gas, roll into the gas hesitate.. Got on the highway quick but noticed a quick hesitation it seemed when letting off and then back on the gas. I cracked it W.O.T today about 10 times just to find out what would go wrong. Guess I found out... Then got home let it cool down for about an hour. Started her up and didn't get 3 miles after a couple red light stops it stalled out and re-started...Hmmmmm.....Fuel or spark??? Tomorrow let the games begin....
