99 miata no spark when engine reaches operating temp
I have a 99 with fm2 turbo kit and hydra ecu. The car will start up just fine and idle smooth when the engine is cold. After sitting and idling up to operating temp the engine will then die and not restart. It has even died on me while driving. After letting it sit for about 15 minutes it will start right up again but die when it gets back to temp. I used a spark tester and have no spark on any cylinders when this occurs. I've replaced both the cam and crank sensors with aftermarket units and it hasn't helped. Any ideas?

Do you have a theory that explains why the ecu COULD be the problem?
If the problem ISN'T under the hood but rather in the ECU, that would lead me to believe it is something to do with your tune and maybe some compensations that happen when the car gets hot. This seems... Unlikely.
What would be helpful is a datalog of the event. Datalog every field it can output and share it here.
