All of the above factors may impact power in moderated multiple regression. Measurement error can reduce power by increasing the noise in the data, making it harder to detect significant effects. Sample size can impact power, as larger samples tend to have more statistical power to detect effects. If the variance of the predictor is smaller in the population, this could reduce power, as it may be harder to detect a significant interaction effect.
