Hi... I have an '02 standard Bonne that also had (1 1/2 years ago) an intermittent no spark/no start condition. Towed it to the dealer when (luckily) it was happening. It turned out to be an out of adjustment (from the factory) pick up coil. The pick up coil is located behind the R/S engine side cover. I'm a regular on a different, very well looked at forum (Delphi New Triumph Bonneville). Nobody else except me and you have had this intermittent no spark thing....Lucky us.....Good luck to you
