When turning on power display reads 128 then error code r 13, after this it say's spa on but the temp reads 126 and the water temp is only about 68 so the heater never comes on.

This is not an error code. 128 r13 is the normal programming or software version for your model. you need to press the spa on button again, make sure the temp set point is higher then the actual water temperature

Mastertemp 300 reads 128 r13 when breaker is turned on, then goes blank. any ideas? just replaced control board, transformer and ICM.

Do you have automation?
If so, Is it in Auto?
You still need to, Manually press the Pool or Spa ON button.
The 128, then the R13 are = Normal.
They are just confirmation of firmware numbers and the Revision of the software Logic.
Then if the Heater is NOT on, display will go blank.

What r13 code mean

There is no r13 code on your heater. The r13 flashes everytime you turn on your heater, wait, then see if it fires, if not, you will get an error code starting with EO then a number, or the "service system" or "service heater" light will come on.

After 128 r13 displays, service system displays. What is wrong?

A lot of things could be wrong. Sounds like your not to mechanical, you could start with the air flow switch. I think it would be safer for you to call a heater pro.
