citroen xm 2.0i bj.90

hello, I have problems with my xm. I drive with him and suddenly he goes out, but unfortunately he doesn’t get back to me. he doesn’t get a sprite anymore, but when he’s cooled down, he goes back. what can it be? then my tacho doesn’t work anymore, why is this? then he always clacks every time he tries to set fire, the lass turns but clean. thanks for euro help. lg kathrin
