Engine trouble? Interruptions while driving?

I drive an Opel Vectra C GTS 211 hp.

It had been running very reliably up until then. However, the following problem suddenly arose while driving:

While accelerating, the car suddenly braked, and the check engine light illuminated briefly. The ESP light remained on the entire time. The deceleration wasn't a complete stop, but rather jerky, as if you were briefly pressing the brakes.

Then I depressed the clutch, gave it a little gas, and everything was fine again. I didn't have to restart the engine; it seemed to still be running.

Another thing that's noticeable is the "ESP light," which stays on. It's off by default and only comes on when, for example, the tires spin. Or you turn it on/off yourself.

I then came up with the idea of ​​simply turning on the ESP light before every trip (which deactivates the skid protection), but unfortunately it happened again today….

The strange thing is, nothing happens for weeks. And then suddenly, out of nowhere, it comes again.

Also, this only started happening after the new tires were put on. Could this be related?

I would be very happy to receive helpful answers.
