I'm driving along when without any apparent cause the
speedometer drops to zero. Cruise stops working and odometer
stops turning as well. Two to five minutes later it all
functions correctly.

I had the same Speedometer problem some years back. It was the battery (NiCad) on the instrument board.

While you're in there changing the batteries, look for cold solder joints. I found a half dozen in my instrument panel cluster which were causing my temp gauge to wig out, my SI LED's to flicker, and my right-turn signal to stop working.

I just pulled my Active Check control panel out last night and found cold solder joints on there, too. Looks like it was a common problem, and I expect I'll find a similar cause for my intermittent cruise control and non-working seat memory.

Luckily it's a cheap, easy fix :)
