Try a different outlet. If it continues, it's a bad plug and/or cord. If it
doesn't, it's the receptacle or the wires connected to it that's bad.

Yes I had this problem, It was one of the screws that you use to wire
in additional outlets. It had backed out and was shorting to the metal
box and triping the breaker. Tightened it up and all was well. Remove
power 1st.
