Ignition circuit- hard to say if it's the coil or hall sender though, they both have the same habits when worn. Carry a spare of each if you can.

Might be worth pulling the plugs just to give you an idea of engine health too.

ill change the coil pack on tuesday and let you no if its sorted it

after driving the car today the car is cutting out whilst driving normaly

do you reckon its the same problem

if its cutting out and then kicking back into action again then i reckon its 90% hall sender problem.
