I am having a similar problem to Grant1. The car runs about 45 minutes, then the ignition cuts out. The rest of the electrical seems to be fine, even though the car is coasting in gear, but not running. The ignition may kick in again, or not. This happened maybe four times on the drive home last night before it died and stayed dead. It started again this morning. I left it to idle in the yard, and it died again at some point within an hour. It wouldn't start again until 5 or 6 hours later. The ignition control module was swapped after it died this morning with a new one without effect, but now the car is running with the new one in.
I tried the heat gun suggestion, but it was inconclusive because I couldn't get the car to die.
The car definitely does not have spark coming out of the coil's lead to the distributor.
I've read the posts about the NTC sensor causing similar behavior. Will the car actually not spark if a bad sensor has heated up?
This has happened before when it is cold and wet out, but the usual suspects have already been replaced. And it wasn't wet last night or today, just cold. (Around 25 degrees last night, and 20 this morning dropping to 14 now).
As I post this, the car has been idling for 30 minutes.
Any thoughts would be appreciated.
Thanks!
