Kenn, the first thing I would check is the plug wires. The boots on the plug end can develop cracks and leak the spark to the head. I had this happen on my 87 9000 turbo a few months ago. Also plug wires can simply start to fail internally and just not deliver full spark.
Also, when you said it seemed like the transmission had disengaged did the engine rev higher without the expected acceleration or did it just seem sluggish? If it was just sluggish I would definitely look at replacing the wires. And use the Bosch wires.
