In the previous times she would start after 2 or 3 attempts and than it wouldn't bring any trouble for months...
This time however I got it to a nearby parking area with a lot of trouble, gave the car some rest after witch she started again. We decided to call it a day since it was already getting late, so I was on the way to get my bud home and it stopped again as I just went past my own house

Now the symptoms:
She cuts out as if I would turn the key to the off position (and the green key light in the desh go's on).
When I give it some taps on the steering column all the lights light up briefly.
After some firm taps the lights stay on (as if its the light check before starting the car).
My guess is the key mechanism but I'm not sure (haven't been under there yet)..
Am I right? Is this common? If yes, what is it and how to fix it...
Many thanks in advance, this is a bummer since I really want to get started on my arm long mod list
