Help please : Lake Water Pump trips

Hello I seem to be having a problem with my lake fed waterpump breaker tripping. This only started happening today after taking a shower I reset the breaker and I can hear the water filling up again and the pressure works fine for roughly 2 to 5 minutes as I run the water.. The pump cycles between 50-65 pounds pressure..and then.. Pop.. Breaker goes and pressure drops to 0 again.. Reset the breaker.. And same same.. Any recommendations?… I was thinking I should get electrician to come in and replace the 20 amp breakers.. Thank you all in advance Matt
