ok, I've picked up the '84 Daytona that was described as having a '30 second cutout'

Whats actually hapenning is that from stone cold it runs for maybe 5 to 10 mins, then won't restart for a while. When it does it only runs for a little while. Its not the fuel system and the coil is ok, so we're down to the HEP or a wiring problem from the HEP or to the coil (or at least thats whats on my list).

I have the good HEP from my '87 SC, is it interchangeable?

No, I believe 84-85 is one unit, then 86 and up is another.
