First noticed the problem on Saturday. The engine shut off at a stop sign, but restarted right away. Problem recurred Tuesday night, but would not restart for 30 minutes
Engine shuts off while driving, will restart on 1995 Acura Legend
I would suspect some kind of heat sensative electrical concern - as in with a fuel pump or ignition control component. Any way you look at it, testing will need to be performed at the time a failure occurs, to see what is missing - spark, fuel, air... Good luck.
