MISFIRING, SHUDDERING, CHANGED SPARK PLUGS, RUNS GREAT, TURN ON AC, MISFIRING, SHUDDERING.

2006 Dodge Ram • 90,000 miles

Check engine light comes on one day. Car shudders and I grab the code and a cylinder is misfiring. I change out all the spark plugs the next day. Everything runs great for over 50 miles. I turn on the AC. As soon as I do this the exact same thing happens. Shudders and misfires. What is the most likely scenario here?
