citroen ax wont start?

its a cit ax tzx, the car idles fine when waiting in traffic etc then just cuts out and wont start for about a few mins. it turns over ok. ive wiggled the wire connection plug on the front of the inlet of the injector (mono) and it has helped sometimes but not this time. this happens when hot and cold
