LT8S ECU`s Yellow light SOLID

I have a 93 rx7 with a LT8S. I noticed that once the car is driven on a hot day (87 degrees F) for 20 miles and then parked (switch off), If i try to restart it once I`ve turned it off, it will not start. I`ve also noticed that time the yellow light is solid. (which is supposed to flash when cranking)

BUT, if i leave then car for 5 mins and then restart it starts up fine and runs like a charm. I know it`s not motor related but maybe the ECU or something electrical.

NOTE: i have already changed my igniter and crank sensors and checked the connectors, however, I`m still having this problem intermittently.

please advise me what is the best solution to this problem.

Best Regards,

when youve switched it off.
and you come back to start it.

while its cranking(during the period were it dosnt start) does the orange light flash while cranking?

it should remain solid when your not cranking.
it sounds to me like a faulty cas or wiring.
