Oven randomly shuts off

Inspected the whole thing no burn marks anywhere on boards everything seems to be in pretty good condition but the oven randomly shuts off usually doesn’t even achieve the set temperature. By shut off I mean it just turns off the baking process as if I never set the bake. The surface burner elements inside the oven seem to be working good and fine customer says it shuts off randomly but for me I noticed it shut off when I open the door The third time while running the oven so I’m not sure if it was a coincidence or if maybe something is loose somewhere inside where I couldn’t see.. I had this issue with another dacor but that dacor completely shut off this one just turns off bake. This one is a freestanding range with the control clock that pops out when you press on it.
