I just got the radiator back in tonight and drove about 15 miles with both highway and stop and go driving without any problems. I am set up to check for spark should it fail again. Would an intermittent crank sensor cause a code to be stored?

Although it was pretty cool out when the engined failed (my experience has been more ICM failure on hot summer days), this is my primary suspect until I prove otherwise. Do the testers they use stress it to cause weak ones to fail.

Pretty good shape there; corrugated tubing around the coil wire.

I forgot to mention that I replaced the cap & rotor when I put the intake back on - used Echlin from NAPA, but am willing to go for Delco if that may reslove the problem. A copy of the TSB was included and I recall seeing one a few years ago when I replaced these. The problem is I don't see any vents on the bottom of the distributor - even considered drilling some holes, but haven't. Any thoughts on that?

I really appreciate all the feed back from everyone. I have 6 people going in different directions in 5 vehicles every day and having this van out of service is a major headache. I could probably drive it and baby it along, but no one else can drive my manual trans truck. I plan to drive it for the next couple of days, but from what I have seen in other posts this may be something that will take some time to track down. Plus, if it is a heat issue, having the engine cover off so I can quickly troubleshoot may not be a good thing.

Thanks again.
