Keg washer pump is jerking

[Pdaigle]

I builded a keg washer pump with a jet pump, it seems to be running fine for a few minutes, transfer my kettles and to kegs with no issue but after a while the pump start jerking and I can see the pressure gauge going up and down and then it shuts off my breaker. Is someone experiencing the same issue, I don't know much about pumps and need help.

here is the pump I bought.

Difficult to say what might be wrong. First thought is your supply water is insufficient causing the pump to suck air causing the jerking. Fill a large container to draw from to see if the jerking stops.

Its already from a large container but maybe I should have more water. Alsofrom my kettle to pump I use a silicone hose and all other hoses are garden mesh hoses so maybe this could be my issue?

Are all the hoses the same inside diameter? Outflow can be a smaller diameter, but not a larger diameter.

1/2 inch but I really think I should change the silicone one
