The hotter it gets the longer it runs. The longer it runs the more power it uses. The more power means if the supply cable is on the light side then you will experience the exact problems you are having. I use 8 b&s wiring and anderson plugs on all my fridge lead and wiring from auxillary battery...regardless if fridge is only 1 meter from the battery. Overkill but I never have power problems.
Do, as what has been suggested, and upgrade the wiring and termination plug (swap to anderson plug for a tight connection and ample power capacity to handle the fridge.
I have also added 3 x 80mm computer fans via a thermostat, that attaches to the side of my 85 litre fridge and comes on at 26 degrees to supply more air flow...thus helping to lower power consumption.
