The direct ignition cassette can fail causing the engine to die while driving, and/or it will crank but not start. The engine may also have a rough idle and run roughly. Diagnosis may discover trouble codes for random misfires.Google+

The sensor has been on for some time and they told me it was the ignition coil and that eventually it would
leave me stranded. 6 months later its been ok... until a couple of weeks ago. Twice it has shut off while
driving and idling has gotten super rough. Today, it kept cranking and
wouldn't turn over. Eventually it did and it was a rough ride.
car just dies while driving...without any warning!!!
haven't had it diagnosised yet.

engine warning light came on. code said to replace direct ignition coil. Replaced and ran fine for a few days, now have the same problem again, only worse
misfire on 3 and now it will just die after I've been driving, also a very rough idle. Sometimes ok and then bam the rough idle starts. I can shift into neutral and restart but not trustworthy. I just spent 2800 having a new head gasket and repair on cylinders 1 and 3. Mechanics are stumped. They also replaced the ignition module.

My engine fails to start and then when it does it idles roughly, runs roughly all the time. Sounds like the engine is "skipping"
