Raspbery with Strompi stops working after X minutes


I’ve connected the V3 StromPi on a Raspberry 3 and I’m using a 12Volt power supply. The power supply is originating from a car battery (but this time inside a boot), from the battery I’m using a 12V DC DC converter. The output of this converter (12V) is connected to the StomPi.
The problem is that when I boot up the Raspberry everything looks fine, the Raspberry boots perfectly and I can use the mouse, start an application etc. Unfortunately after 2 to 3 mins (roughly) the Raspberry suddenly stops completely. Nothing is working anymore. The blue HDMI led is switched off and the monitor has a black screen.
Any idea what is happening? Can the StromPi handle 12V as input? Will the Raspberry be powered with a good stable supply from the StromPi? How can I debug/analyse this problem?
Please help as I don’t know how to address/analyse this problem?
Thanks. Rene.
