Pump Problems
It does sound like the intake pipe may be cracked. Do you not drain it down to the lake when you close up? I'd suggest you invest in another section of plastic pipe and run it over the ground into the lake and retry the pump to test whether the it still continues to cycle frequently. If it doesn't, then you've probably identified the problem -- cracked pipe.
If you do have to replace the underground pipe, I suggest you run a larger diameter section of pipe from where the water line enters the ground at the pump end, down to where it exits into the lake. I think my builders used 3" pipe. Use that as a sleeve to push the smaller water pipe through. That way, if you ever need to replace it again, you won't have to dig it up, just slide a replacement through the same sleeve. Also provides some protection for the water line itself.
One final suggestion: I installed a plastic ball valve a few feet past where the pipe enters the lake. In the fall, I open that up and it back drains the line down to lake level.
Good luck.
