My 1998 Chevrolet Tahoe kills while driving. It has happened only on long trips and the service engine light doe not come on. It starts back up and runs fine, but the engine has killed more than once, just not back to back. One time after the engine killed, I drove to gas station and it died while idling. I have been told that the electronic control module (ecm) could be overheating on long trips but I just want a second opinion. I went to a service station and the guy said if it didn't relay any signal to the computer via the engine light coming on, he could not diagnose it. Any help is greatly appreciated.

This happens when the ignition can't read the key. If it is not starting when it does this. to fix this leave the key in the on position not running for 10 min or till the security key flashes and turn it off wait 5 seconds and then start it. If the light stays on and it is running just drive it like that put some electrical tape over the light. ours has bin on for 84,000 km and this no start thing has happened a few times this is a common gm problem. hope this helps you.
my younger brothers' truck did the same thing and there was a relay up under the dashboard that would get hot and shut of(kind of a circuit breaker unit) most of the operating systems will flash at you when only battery voltage is available which explains the lights coming on..these newer trucks also have a performance chip in the system that will act up when it gets warm also..replace this and you may be ok..let me know what happens also.. good luck.
