Dryer lights up and chimes but turns off after I push start

I have a Kenmore Elite 79681073210. It was working for awhile but then it started shutting off when I hit the start button. I’ll push the power button, the lights turn on, it makes the beeping noise, I push start and then it just…shuts off. The “check filter” light also blinks before I push start. I tried changing the door switch and nothing. Tried cleaning out all the lint I could and nothing. It’s driving me crazy. Can someone please give me an idea of what the problem might be?
