As much as this may seem counter intuitive, it is good news.... Intermittent problems are hard ( and very $$$) to fix as possible solutions are tried out at customer expense. Once it is truly "broken", the real source becomes obvious..... and the fix is enacted. From a problem with an intermittent car fuel injection component...... $2000 expended on intermittent "solutions" and finally the $12 relay was replaced to fix the problem.....after it finally did fail.

Then last week it stopped firing completely and hasn't since.
