Get a second opinion (second gauge) do verify you actually have 73psi, Also check to see if it has a adjustable pressure reg, and maybee a kinked return line,
Where did you tap your system to get your pressure?

sorry, lt guy here, well the only other thing I'd do is check how many volts your getting to your pump. I'm not sure but if your voltage is spiking maybe just maybe it's causing your pump to be superman.
