Doesn't have to be that long... I'm taking a class at the local community
college which is up on a hillside, and coasting on the way down (within 1/2
a mile I'd say) it feels like somebody suddenly yanked the emergency brake
and let it go, and I'll lose about 10 mph. This is well before the engine
gets warmed up, btw. The speed will continue to drop from there if I let it,
or if I goose it back up it'll hold for a bit.

Cya,
Robert

Thanks, Karl -- this has been discussed twice in the past two years, in
depth.

I wrote the thing up in the wiki, which is down.*

On long downhills, when your foot is off the gas and with the transmission
in gear so the engine is being overrun, the ECU cuts off all fuel
delivery. The pistons go up and down, sucking in and expelling cold air,
but with no fuel to burn, the engine will go dead cold.
