I've had this problem with a bad coil.  Fails when hot, works when cooled down. It will run hot, but after sitting it heat soaks and fails. Cheap and easy to swap before you get in deeper.

A gremlin from the past seems to have reappeared on my '84 Vanagon (1.9L) engine.  It started the other day after I went to move my van after bringing my Son home from high school (10-mile round trip plus plenty of waiting time in traffic at high school).

Engine turns over fine, but does not fire.  Possible smell on unburnt fuel.  The tach need flutters a bit while starter is engaged.  After leaving van to cool down for a few minutes or longer, it starts and runs fine.

My first suspicion is that there is dirt on the contacts in the big connector between the fuel injector cable and the fuel electronic control unit, and that I should clean the contacts on both sides of the connector with CRC-626.  This was a problem many years ago, but only showed up in cool damp weather.

My second suspicion is that their is a problem with the ignition control unit.  I replaced that unit in 2003 when I put in a Boston Bob long block.  The fuel injection cable and the fuel ECU are the same ones that were on the van when I bought it in 1997.

I would appreciate the wisdom of the list in solving this problem.
