Volvo 850, S70, V70 Lawnmower Syndrome Theory - Video
This video explains the lawnmower theory in case anyone want to watch and link later.
The symptoms are, all of the sudden your car does not start. Usually after a brief start and shut down, as in moving the car 20 feet or so. Far enough to get the "lawnmower" out of the garage. The car sits a little while and when you return, it cranks but will not start. So you go through the process of trouble shooting the no start condition and learn that you have little or no compression across the board.
The solution is to pull the plugs, air them out or replace them, pour a little oil in the cylinders to wet them with oil (instead of fuel), put everything back together and crank away. Within a minute the car will build the compression needed to fire and your problem is gone, likely never to return.

It's called fouled spark plugs, and that's all it is.
