I need urgent help

On my LR Freelander 2.0Di y.2000 I have very unusall problem. Often (not all the time) when I engage flashing light on engine loses electricity and dies. In that moment all indicators (speedometer and rpm) goes on 0. If i pull it back when the car is still in motion engine starts to work, but if it is in still it dies.

It happens only sometimes, it seems that problem is more frequent when it is hot. When it is cold it seldom happens.
At first it only happened when I put the left flashing light on, but now it hapens on right too. Than it used to be ok when on start problem wasn't active everything was ok. But now sometimes everything is ok when I start but during driving (after afew flashing lights activating and everything ok) it suddenly makes a problem.

Oh yes and sometimes it doesn't want to start at all. Engine is dead(no sound at all), but when I take out the key and press unlock button on remote engine afterwards start ok.

Please help, my wife and kid are driving the car most of the time.

Thank you very much

Hi, I have studied the electrical diagram for your car and I think that you have a bad connection to the ignition switch.

You should never allow young Capra behind the wheel
