Re: motor shut off while driving.

It could be a broken timing belt or a dropped valve seat.
Check the belt by turning it over and looking in the filler cap hole for movement. If nothing is moving the belt broke.

If the belt is all right it is more than likely a dropped valve seat on cylinder no. 4. The noise you are hearing is the seat hitting the cylinder head and the piston.

I don't think the noise is a valve hitting a piston because Ford hasn't built an Escort engine that is an interference engine since 1986.
