C200 1997 - speed drops/limited to 40mph spontaneously

Hi my C200 1997 Auto 5 speed has had new speed/valve sensors 8/12 ago. Been fine since but now having occasional episodes of speed suddenly dropping to 40mpg from e.g. 70mph on the motorway - resolved itself shortly after. Other occasions not got past 40mph from cold even on motorway slipway. Resolved by restarting car. Any ideas to the cause of the problem? Thanks.
