Over the range MV Oven shuts down from heat

Question

Hi, I have a new Maytag MMV1153BAW P/N 8102P27160
When using with vent (ducted to attic) on high, it will shut down after a few minutes. It will also shut down or not work if the range below is cooking. It is in our vacation home and hasn't been used over 10 times. It eventually resets itself after hours and hours, but will shut down even when heating up coffee in a coffee cup. Thanks
