Alrighty so when it warms up and after about 10 minutes of driving my miata stalls-out.

Good fuel, good spark, i give up!

Maby CAS needs adjustment or COIL has crap in it?

It is so hard to diagnose because it only happens when I am driving after about 10 minutes. Let it sit and cool for 1 minute and starts right back up and goes for another few minutes.

ANY HELP or ideas are appreciated.

 

I had a failing CAS do the same thing once.

 

Hummm... Is there any way I can make sure it is the CAS before I replace it?

Any other ideas?

 

Try and start it back up right away after it stalls. If it cranks and doesn't start, see if the check engine light stays on while you crank. If it does than its most likely the CAS.

 

I tried that. It cranks good but does not start right away. The check engine light only comes on right when it stalls and then goes away.

 

When it cranks but does not start does the CEL stay on or off while you are cranking?

 

Check the codes in the computer noe. The code is stuck in the computer, so just read it.
