i had same problem last year,tried swapping distributors & ignition sys. lastly i transfer the whole engine to a different chassis and uses that same s300...and it works fine.so i concluded that it was my ecu wiring harness. may be u could try using different wiring harness..may be thats the prob.

we figured it out, it was bad soldering on the CN2 4 pin header

thanks
