Oven keeps cutting out while using it

Overheat condition all cookers have overheat protection built into them for safety this will cut the power is the oven reaches a set temperature and overheats, this will shut the power off to the elements and will not re-energise until the cooker is cooled or it may trip the thermal cut out and this may need replacing.

This is a good thing never try to remove or bypass the thermal protection you have built into the oven its there for safety reasons and could save you life one day.

Investigate possible reasons for the oven to overheat for example badly fitted oven , blocked air flow , thermostat issues or even the cooling fan failed.

It could be that the thermal cut out is operating to early so a temperature check would be wise on the oven to ensure this is not happening.

Oven thermostat all cooker and oven have at least basic on off control of the heater element using a thermostat to control the electricity to the element. This will allow the element to activate when the temperature reaches a too low temperature and turn off again when the temperature starts to get to high for example an oven set at 100 degrees C would turn on at 80 degrees C and off again at 120 degrees C and continue this cycle until the oven is turned off or temperature adjusted.

Newly fitted appliances can be fitted incorrectly which could cause bad air flow or no ventilation or it could be a a faulty component within the machine. 

Faulty element that can heat then break contact and fail or more usually trip out the electric supply as soon as the element energises.

Switches can be faulty or worn internally and can sometime disconnection power to the elements usually you can tell by the feel of a switch if something is not right with it.

Timers PCB and electronics these as we all know can be temperamental if faulty, if a faulty joint or track disconnects while the board heats this would disconnect power. The relays could be contacting badly if old or worn. 

As you can see a lot of issues can cause this problem so logically work your way through the possible causes and test the components and use you knowledge of the systems to troubleshoot.
