Robert, 
Mine did the same thing many times, except that now is dead-dead-dead.
Initially it appeared to be temp related, it would restart after a cool down, but eventually if refused to start. No codes, Brain is out for diagnoses.

I have ruled out failure of the coils as they are all dead, so must be a control issue.
Replaced both the flywheel sensors with no change. I'll keep the list advised of any progress here.

Tow bill got pretty big!
