Now, the dryer starts, runs for 5 minutes

I have a Maytag elec dryer that is less than 2 years old. Now, the dryer starts, runs for 5 minutes, then stops with the warning on screen, power failure, please press power button to start again. Press the power button sometimes restarts for a few minutes then stops with same explanation in the screen as before or it will not start for a bit before and then will start with same issue of shutting off. I have replaced the thermal fuse and the thermal shut off switch. Changed nothing. What do I do next?
