I would look at you secondary ignition components. Spark plugs, plug wires, coil packs, ignition module. you should see if you have codes for misfire. if not drive with a scanner on and watch the misfire counter.

spark will always look for the easiest way back to ground. under a load it may be easier to jump outside the system instead of jumping across the spark plug gap.
