struggling to take off from stand still

[libz05]

hey guys,
need some help and advice

so recently ive been back in the liberty and relised sometimes this happens:

so im at the lights lights turn green and i accelerate mildly and sometimes it struggles to go for like a sec then picks up. ive relised when this happens the cruise control light and a few other lights flash and turn back off immediately.

does any1 know what this may be ? or does it jst mean time for a service because it is due for a service very soon

thanks in advance

sounds like a loose battery terminal or something shorting out.

But my first question always is

What has changed since just before it started?
