Surely if you strip gas out of galaxies, you stop AGN activity?

The galaxy from which gas has been stripped, yes. But does the stripped off gas deposit onto the interacting cluster leading to refueling of a quiescent AGN in this cluster?

Observed instances of massive gas inflow and AGN restart due to cluster-cluster merger?

Works such as [Acreman et al. (2003)](https://academic.oup.com/mnras/article-lookup/doi/10.1046/j.1365-8711.2003.06504.x) have demonstrated via simulations the possibility of gas being stripped off a galaxy due to interaction with a galaxy cluster.

Have there been confirmed instances where a cluster-cluster merger led to the infall of huge amounts of gas onto one of the clusters? Further, have there been instances of cluster-cluster merger leading to restarting Active Galactic Nuclei (AGN) activity?
