After nine games without a league victory Livingston have now won two on the trot thanks to some ruthless finishing at Fir Park.
Just as they did against the same opponents on the opening day of the season in August Livingston raced into a three goal lead and never looked back.
The result leaves Motherwell experiencing a drought of their own following six winless outings since upsetting Celtic last month.
While the result suggests they were lost without boy wonder James McFadden it didn't look that way in the early stages.
Home skipper Scott Leitch sent an improvised shot narrowly wide and Derek Adams and Dirk Lehmann both headed over when crosses from the right asked questions of the visitors defence.
But Motherwell had no answer in the ninth minute to a left foot rocket from Lee Makel that found the top corner of the net from fully thirty yards.
As play raged from end to end Motherwell still struggled to turn their superiority into goals with Keith Lasley shooting low and wide.
Although attacking sparingly Livi showed a sharper cutting edge and in the 24th minute Burton O'Brien's unselfish cut back deserved a far better finish from Makel.
Motherwell were genuinely unlucky six minutes before half time when Lasley's fierce shot at the end of a thirty yard run forced a spectacular one handed save from Javier Broto.
But any hopes the home side might have had were dashed by two goals from substitute Cherif Toure-Maman in the opening twelve minutes of the second period.
His first goal owed much to the poor positioning of keeper Stevie Woods while the second was a tap in from Eugene Dadi's pass.
And although debutant Khaled Kemas pulled a goal back with a sweetly struck volley David Bingham and substitute and David Xausa underlined Livingston's supremacy, and added to Woods embarrassment with a pair of impudent chips
