Jonas,
Sounds like a heat soak related open or short circuit. In swapping the coil
and condenser, you arrested the key suspects. I would bet even after the
swap, the condenser is shorting when hot. Other possibilities are a carbon
track in the distributor cap from center contact to one spark plug or to the
distributor housing, or a breakdown of the coil to distribution high tension
wire insulation, or an open in the coil low voltage wire or ground. I
suggest first moving this wire so it has different near touching or
grounding points, exchanging it end to end would do this. Next would be a
careful inspection of the distributor cap. Then running a parallel patch
wire from ignition hot to the coil. After that I join you in confusion. A
graduate of the US Army Command and General Staff College share with me one
of their teachings "If you are not confused, you do not understand the
situation." Perhaps we "understand" it together.

Subject: [Healeys] Ignition Problem BJ8
For the past 2 weeks, my car has been starting just fine, and can run at
idle indefinitely, but within minutes of taking off for a drive, conks out
and will not restart - no spark. Initially, after a few minutes, the car
would restart and run for about 30 to 40 seconds before conking out again.
Finally it would not start at all. At that point, I swapped out the coil
and condenser with one from an operating car and it still wouldn't start.
Over the weekend, I disconnected the "security circuit" at both ends, and
also discovered that the nylon washer /capacitor/ground/ points post in the
dist.
Were assembled in the wrong order. Upon fixing this, the car fired right
up.
Today, it fired right up, warmed up to operating temp, and within 1 minute
of running, conked out and will not restart.
Any ideas?
