When engine stallled, were the dash indicators lights showing? Yes once it has died but not before it dies. I have noticed a couple of times I get a couple of warning lights that seem like they shouldn't be on (brake, check engine) then they go away and no codes are present.
Were you able to restart if the accelerator pedal is depressed? No it trys to start, gets to about 400 rpm and dies again, over and over until the battery cable is removed for a few minutes or it has cooled off.
When engine is running, what is the idling speed? Normal idling speed is about 800 rpm.
Does turning the AC on cause the idling speed to drop before stabilising? It seems like it drops momentarely then recovers in about one second. Problem happens with AC on or off.
When the problem first started, it would stumble and die while driving at highway speed, I could put it in netural and cycle the key off and back on and it then would restart and run just fine, it has been very intermittent but gets worse with warmer weather.
I'm leaning to the ECM since interupting power seems to help. I can remove the battery cable and things seem to reset but it may go a mile or 50 miles before it does it again. It has happened while ideling and also at speed. Sometimes it just shuts off and sometimes it feels like it is missing ( for maybe 5 seconds) the shuts off.
