What could be causing my Vauxhall Corsa to suddenly lose power?

I have a 2010 Vauxhall Corsa and it has been running fine until yesterday. While driving, the car suddenly lost power and the accelerator did not respond. The engine was still running and there were no warning lights on the dashboard. What could be causing this issue and what can I do to fix it?

It is also possible that there is an issue with the electrical system, such as a faulty sensor or a loose connection. These problems can also cause a sudden loss of power. I recommend having a qualified technician inspect and repair any electrical issues.
