cooktop tripping braker

After cooking for a while on the cooktop, it will trip the breaker. It does not trip right away, and sometimes it won’t trip at all. Any ideas?

Thanks in advance

Sounds like a loose connection somewhere in the system that shorts to ground or neutral when things heat up.

After a little more investigating, it seems that the left rear burner will not cycle. It just keeps getting full power even if you turn it to low. Will this cause the breaker to trip?

It’s possible that that’s the culprit.
