Hi guys,
For the last few years I've had an intermittent problem and would be extremely grateful if anyone can offer some help.
Issue:
When I insert the key into the ignition and turn the key to start all the electrics would completely cut out - no display on the dash - electric windows, central locking - basically the entire car with no electrics as though the battery had been disconnected. Position 1 and 2 on the key are fine, it's usually the final turn of the key to start when you would here the tick sound and then all electrics shut down immediately.
An example of the issue can be seen here:
It would sometimes (but rarely) occur when I press the unlock button on the key fob.
Last night, for the very first time, I was driving and the ESP warning on dash appeared and the stereo shut out for a brief second before immediately starting back up. Managed to drive for 5 more mins and parked up. As soon as I took the key out, all electrics cut off.
Other info:
Whenever this happens, I normally flip open the bonnet and disconnect the ground cable from the negative terminal on the battery. Wait a couple of seconds and then reconnect.
Car starts up perfectly normal. (Sometimes I need to disconnect and re-connect a few times though).
The problem is intermittent and hard for me to know what the issue is. I've tried cleaning the ground cable from the battery terminal over a year ago but that didn't seem to do the trick as it still happens to this day.
I'd be very grateful if anyone help me to diagnose the issue as it's been happening for so long that I've gotten used to disconnecting and re-connecting. However, since the issue with the electrics cutting out while driving last night, I'll now have to take it more seriously and get to the bottom of this once and for all.
Would be really grateful for any help as it's stressing me out.

Edit: Battery is only 1 yrs old (and even used to happen when it was new), so highly doubt it's a battery issue.
Voltage info from the vehicle dash last night:
