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.

Starts fine while engine is cold, but upon trying to restart while engine is warm, cranks but no start. Also had engine die while slowing down to stop. Replaced plugs, fuel filter & cleaned throttle body intake valve. Engine would not start after warm & must wait a period of time before restarting engine. Engine seems to run smoother with new plugs & filter. Fear it's the DI cassette, but going to try the CPS first.

I had the same problem car turned off every 20 mins or so and wouldn't restart until cooled off, change the knock sensor and oil pressure sensor, checked for cracked hoses and stuff was about to junk it but decided to change the direct ignition coil and sure enough solved the problem. I opened the coil by removing the plastic parts that goes on top of spark plugs and i could see cracks on the blue box and some melting.
