if you are losing fire to the plugs there is a good chance it is ignition related component possible crank sensor or ignition module problem.

doubt it would set a code for either one if failed plus his post specifically says the plugs will not refire till it sets for a awhile I take that to mean no spark.

obe,
I had a similar problem on a different car.......
Turned out to be the ignition coil. The coil would heat up and build-up enough internal resistance in the secondary winding to not fire the plugs. Let it sit for about 5-minutes, the coil would cool off and the car would run fine until the coil overheated again.

Might not be your problem but it's worth checking out.

I had another car that had similar symptoms except this one would run days or weeks and then one day just die. Let it sit for 5 or 10 minutes and it would fire and repeat the problem. I suspected the fuel pump but wasn't sure because the problem was so intermittent. I could never get it to die in the driveway; it would only die when I was miles from home!

Anyway, I replaced the fuel pump and the car never died again! Guess I got lucky; I'm usually not a "Parts Changer."
Good luck,
Phil

read his post wrong.

Needs to check for crank or cam signals before throwing coils at it.

Another tip when measuring the resistance of the coils you do it when it won't run.

A lot of auto parts store have ignition module testers. call around you will eventually find a place with one.
