This really is consistent with a gear box issue. From what you are describing the pump is not priming the system fast enough and resulting in your issue. This issue is likely not a bad pump but rather a fluid glow issue. What I would suggest as a first step is to have the gear box fluid changed and the cooler lines cleaned and see if this corrects the problem.
