Synopsis
B737 MAX flight crew reported an engine failure during descent. Crew referenced the QRH and noticed the engine returned to normal operations. Crew continued and landed normally.
Narrative
On Day 0 I was the pilot flying on Flight ABCD from ZZZZ to ZZZ. Before starting our descent we were giving a hold at 'ZZZZZ' intersection. When we started our descent into the hold the Captain called out 'Engine failure' and we both acknowledged an 'Engine Fail' message on the #1 EGT gauge. The Captain asked me to fly the airplane. I do not totally remember what the Captain was doing at the time; I believe the FAs (flight attendants) had called us at the same time this happened and the Captain was speaking to them. I then grabbed and started looking over the QRC to see if there was any items that pertained to the situation. The Captain then told me he'd run the check list. I asked the Captain for help finding the 'Eng Out' button on the CRZ page; but could not find it because we had started the descent. I asked for this because I feared leveling at FL290 in a stacked hold may be too high of an altitude. I did ask for help locating it again; but the Captain informed me to focus on flying the airplane. Approaching the hold entry; I asked the Captain if I should inform ATC of the engine failure. He told me to hold off on informing them. Very shortly after entering the hold the engine did return by itself to normal operation. Around this time the Captain had the checklist out for 'Engine Failure MAX.' The Captain reviewed the checklist aloud; but did not preform the actions because the engine was operating normally. The Captain then contacted Dispatch and Maintenance Control via radio. They informed us to write a logbook entry. We then made our plan to continue to ZZZ and discussed possible diversions. We landed normally; but while exiting the runway we received an overhead 'MAINT' and 'Engine Control' lights. These issues were also written up. We parked normally and debriefed the flight.
Second reporter narrative
ATC cleared us to descend from FL370 to FL290; with instructions to be level at FL290 by ZZZZZ. After the initial descent clearance; ATC also issued holding instructions for ZZZZZ. As we began the descent from FL370 and the thrust levers were retarded to idle; I observed the No. 1 ENG FAIL flag illuminate on the No. 1 EGT gauge. At that time; the No. 1 engine parameters were approximately 29.6% N1; 556 EGT; and 71.6% N2. There was no associated adverse yaw or any other abnormal indications.When the No. 1 engine generator dropped offline; I started the APU and restored electrical power to the affected bus. As I began executing the (MAX) Engine Failure NON-NORMALS QRH procedure; the Purser called the flight deck. Anticipating that the call might be related to the engine issue; I answered the service interphone and instructed the First Officer to continue flying the aircraft and to monitor the No. 1 engine.The Purser advised that a passenger was upset about being denied access to the First Class lavatory and being directed to use the aft lavatory. I informed the Purser that the flight crew was managing an engine malfunction and advised her that I would return the call once the situation was under control.During the descent and as I was beginning Step 2 of the Engine Failure checklist; the No. 1 engine restarted. The ENG FAIL flag extinguished; and all engine parameters returned to normal as we entered the holding pattern. The engine was monitored for several minutes and continued to operate normally. I then restored the engine electrical configuration and shut down the APU. No further abnormalities were observed.While holding; I established a phone patch with Dispatch and Maintenance Control; advised them of the event; and provided the recorded engine parameters. Maintenance Control requested that a detailed debrief be provided to ZZZ Maintenance upon arrival.We were subsequently released from the hold and landed at ZZZ without further incident.
