I saw this problem with my K3 #4xxx and discovered a large voltage drop between the PS and K3 using the provided power cable. Cured the problem by: 1) shorter & fatter power cable, 2) increased the PS (Astron 30A linear) to 14.5v, and 3) running the K3 utility power calibration _twice_ back-to-back. Why it took 2x I don't know but it's been 100% fine ever since.
