Our Delta did very similar things, I think it's typical of a boat that is;

very deep vee
stern heavy (take a critical look at how she lies in water)
possibly lacks the torque to climb onto the plane quickly

Try trimming all the way in (ploughing) when you start, this goes some way to lift a heavy stern
Lifting foils on engine (cheaper option than trim tabs)
Modify driving technique radically.

Last point is basically to try and prevent the boat flying off the top of a wave, the stern (in a stern heavy boat) would normally fall away dramatically.
I think our boat is slightly underpowered and it doesnt take much to knock it off the plane if you dont judge the conditions right, it then takes some time to regain speed and go onto plane.
