You have already found the EZK computer 700 1987

"its a b280. the number 15 (Coil) terminal has 2 wires 1 that i traced back to the power stage and the other goes all the way to the FI ecu..."

If you traced a blue wire from the coil to some ECU, it had to be the Ignition (EZK) ecu -- NOT the FI. There are no Coil wires going to the FI ecu. None. So when you said you were going to look for the EZK ecu, I replied you had already found it.

Anyway, from your symptoms it's not likely an EZK ECU problem unless it's the Power Stage control wire (green) from terminal 16 going to power stage terminal 1. But I have never heard of that (or the ecu) as causing your problem.

IMO, the most likely problem is the PS connector contacts or the PS itself. They are known to fail, especially with age and due to the heat sink conditions I mentioned before. A bad ground on the intake (2 brown wires) might do it too.
