All power is list suddenly

(1990 Lincoln Town Car)
in Memphis, TN on June 30, 2010
Great car except, on three occasions it has stopped all power lost, for no apparent reason. The first time was about 10 years ago. Hot day. The second time was last year, hot day. and again this year, hot day. The thermostat shows normal, everything seems quite normal, then it slows down and completely shuts down. There is no way to move it even an inch until about safely 2 hours later it cranks right up and and runs like a dream. No one can find what the problem is.

Check water pump at the pressure side, you shuld be able to feel the coolant passing through when the hose is squeezed! If no pressure is felt, then water pump is not working! Replace water pump and both hoses and the thermostat! Check coolant relay switch, it's primary job is to measure coolant temperature and send that reading to the ECM which is preprogamed with operating data! If data received exceeds the value in the ECM it will make adjustments and most likely shut down the operation of the engine to prevent any mishaps that might be considered a safety hazard!
