There are few reasons for this fault, but the main is that you need to open your microwave oven and first check the Fan which is connected at the back which cools the magnetron.
If this fan fails thus results in magnetron being overheated and the thermal cutoff gets open circiut and shuts down whole power of your microwave oven.
Check your fan motor test it straight with direct power
Also check the thermal cutoff.

Let me know after you have done those checkups

This could be a lot of things. IT might be a capacitor or diode. MY money is on the capacitor. Since it works for a minute before it quits.

Toss it out. The transformer is likely bad.

logic board needs replacement if it cannot be reset.

The oven may not be seated properly. check the bushes at the bottom.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Let us know if the hard reset doesn't fix it.
