Narrative

We had just started our descent on the ZZZZZ arrival. We were in the middle of a lav break and when I returned; the First Officer (FO) stated that we had an Engine Stall and Ignition Indication on the ECAM during my absence that quickly disappeared. We then noticed that the #1EGT was quickly approaching Red Line. It fluctuated a couple of times and then gave us an Engine Failure ECAM. We [requested priority handling]; complied with the ECAMs; diverted to ZZZ and completed a safe landing. It was an extremely busy time between running the checklists; communicating with ATC; Dispatch; Flight Attendants and the passengers. There was a lot to accomplish in a short period of time and easy to get off task. We also received other ECAMs which created confusion; such as FUEL Indicating System Fault. ATC was extremely helpful but asked a lot of questions at a critical time. I was able to reload the box; the FO directed the airplane towards ZZZ; we completed the checklists and successfully flew the ILS XX. Once on the ground; Airport Rescue and Firefighting (ARFF) inspected the aircraft; gave us an all clear and we taxied to the gate. All passengers deplaned via the jet way.
