CAR CUTS OUT FROM TIME TO TIME FROM 4 CYLINDERS TO 3 FOR ABOUT 5 SECONDS AT A TIME. DO YOU THINK. ITS SPARK PLUGS OR COIL PACK OR BOTH?

Cuts out for 5 seconds or so from 4 cylinders to 3. I wonder if its the spark plugs or coil pack or both?

It only seems to happen once the car heats up which made me think it was plugs or the coil. Your thought? Thanks
