Clio 197 Cup Cuts Out

Quick question....just last night started car up for it to cut out a few minutes later, started up and revved up for it to move but was very jerky in 1st and 2nd while moving and finally when I come to slow down it cuts out. Start the car up and it just cuts out straight after. Any thoughts what it could be? I've searched the net for people to say crank sensor?

Any help would be appreciated

No MAP sensor has been put in standard, the seals around the MAP sensor was fooked so I replace with decent ones and refitted but still seems it's cutting out.

Possibly a a faulty sensor?
