Zanussi fjs1225 keeps stopping?

My Zanussi fjs1225w keeps stopping once cycle has started. Sometimes it stops straight away sometimes goes for 10 mins then stops, all the lights/readings go off except for on/off and door light, no error code. If I press the start/pause button it goes again then stops after abount 2 mins, I have to keep doing this to get it through the cycle. Any ideas
