Rick,
This is a typical semiconductor symptom. It sounds like the drive
transistor is semi-fried and internal heating during operation is causing it to
malfunction. Return the unit for a replacement.
This type of failure is hard to detect during production testing, as the
unit isn't allowed to get very hot or run for vary long. It would be caught
during a burn-in test, but this type of testing is usually cost prohibitive to
the manufacturer. Typical infant mortality of power transistors can be as high
as three percent.

I don't recall if this was covered in the previous discussion of the
Crane electronic ignition. I just installed one on my 66 Midget and it
seems that the car will run perfectly for 5 minutes and then it will die
immediately. After a "cooling-off" period of about 5 minutes it will
start up and run perfectly. The troubleshooting section in the
instructions does not cover this kind of strange behavior. Has anyone
else experienced this? I am tempted to put the original points back in,
but after shelling out $120 I really want to make the Crane unit work.
You can't get real far driving 5 minutes, sitting 5 minutes, ect, ect,
ect.
Thanks for any help
Rick Williams
