Intermitant Fault with mag 350 MPI

[Dodgezilla04]

mine would do it too. 5-10 minutes and then she'd begin sputtering and crap out on me. 1/2 later, she'd run again.
found it late at night when running it in the driveway... when it started to sputter, i could see little blue lightning bolts under the engine cover...
the coil tower was cracked allowing it to arc to the secondary wire..... killing the ignition. when the coil cooled, the crack shrunk and she'd be fine until hot again..

$54 coil and all is well.
