ANSWER: I have responded to you first question. Please clarify to me whether the vehicle'e engine is running properly and that the only problem is the gauges and the gauge lights?  Do the other lights (headlamps?) also go off?
You need to tell me more: specifically to be of any help, other than the battery and its wiring which I suggested based upon what you described, what else is wrong?

QUESTION: NO, The other lights are not going off , but when that thing happens
all the electricity are effected (Radio , AC , ..) for example the radio
or DVD switch off and starts from the beginning

Answer
Hi Carolyn
Although you added the AC to the list and that the main headlamps themselves are not flickering, that does corroborate my theory that the ground bolt holding the return wires from those affected circuits you list is indeed loose. The earlier problem with the engine not starting is probably related to the same loose bolt because the sentry key immobilizer module (the anti-theft unit) is also grounded at that same bolt.
So look for that group of black wires on the kick panel to to left of your lower left leg, as described earlier, and if you can't find it tell me your email address as I described, and I'll send you the drawing. All you need to do is twist the bolt clockwise with a pliers to make it secure and that may solve this problem once and for all.
Please 'rate' my answer.
Thanks,
Roland
