Toyota 2.2 D cat hardly pulls from 2200 revolutions

Good day, We were on the weekend a few hundred kilometers on the way. On the way my wife suddenly noticed that the 2’2 Dcat (2006 Bj177 Ps) did not pull any more properly. I then tested it, he pulled generally bad and from 2300 revolutions almost no more, like with 100 Ps. Then suddenly, after he was parked, he pulled again about normal. Today back drive, again the same. First he drives normal, then starts again. A motor light does not burn, very funny! We must n anyway make an appointment because of a recall action, but maybe someone can estimate what that is and whether you can drive like this without ruining more… unfortunately the car needs. Thank you, greetings
