Cylinders 2 &3 Not firing when hot

you should have 3 ohm coils with the s
ive had 2 dynas fail on me this way one running stock coil plug boots.
dyna replaced mine for free very good customer service.

I called Dyna and the Accel super coils are correct with the ignition system. The system has been in use for years. I read somewhere the coils due their age could fail due to heat which is why I replaced the 2-3 coil, but same problem occurred. Dyna suggested I check do a voltage test which again checked out ok. They (Dyna) have sent me a shipping box so I can have them check the unit out.

I used the same constellation., except my coils are under my left side cover to prevent heat by the engine.
Dyna S with Accel super coils and ignition cables i have build in 1997.
I have no problems with any parts of it till today, runs like a purring cat..
