OK, if that is an oil filled coil and you have it mounted horizontally then that's most likely the problem. If you want it mounted horizontally then you gotta go with the epoxy "High Vibration" off-road jobs. Oil-filled coils leave air bubbles when mounted on their side and either short-out or overheat (or both).

I promise I'm not making it up. MSD makes a big deal about it (I have mine mounted sideways on the intake as well) and sells their "Hi-Vibration" coil specifically for that purpose. I did a quick Google on the MSD site and found this chat thread from their tech support where the tech guys says "The oil is what cools the coil. When a oil filled coil is mounted side ways it tends to get hot and fail." https://www.msdignition.com/forum/showthread.php?t=1818 I'm also pretty sure the instructions for oil-filled coils always tell you not to mount them sideways.
