Dear customer the problem that you present is known as an emergency/limp mode or there is simply an error code that is activated by the computer causing the vehicle to shut down for some reason. It is actually the solution of this is not very complicated but you need the adequate equipment to know what is happening in your vehicle.
The first is that this type of failure is not noticeable by means of generic equipment. Obd2 Diagnostic equipment are not adequate. The proper diagnostic equipment of your model must have the appropriate vauxhall software for your model. So, you will have access to the error codes or the live data stream.
Usually, these problems are caused by overheating the vehicle components, the most common is that the pump overheats causing it to stop sending fuel and the vehicle is turned off so the vehicle restart normally but does not last much given that the pump is immediately heated, this type of problem does not generate error codes and usually the solution is always to replace the fuel pump
Dear customer the engine distribution system is made up of several sensors that detect the crankshaft and camshaft grades to know when and how to inject fuel when we are having a problem in these sensors or when these sensors suffer overheating problems the vehicle shuts off sporadically and comes back on immediately or in minutes usually. Also that type of problem is due to faults in the wiring not only of these sensors but also of the fuel pump. Therefore it is good to check the wiring of the distribution system of the fuel pump and of the injectors and the injection pump.
Dear customer, i could continue with several causes, but the best way to start is with a computarized diagnostic, but as i said we need an appropiate diagnostic tool with the right vauxhall sofware.
Have you understood me dear customer?
