Hashem is referred to as Maran in a number of Aramaic prayers, such as מרן די בשמיא לך מתחננן, found in Selichos, and brought in Seder Rav Amram Seder Rav Amram (Seder AshmorosSeder Selichos/Ashmoros Page 41). Another example is the use of the term מרן די בשמיא in יקום פורקן.

These show that in Jewish tradition there are examples that show that Maran by itself (meaning "our Master") refers to Hashem. Based on a quick text search, it seems that in Tanach, "Mar" only refers to Hashem is when He is referred to as מרא שמיא, or "Master of Heaven" (Daniel 5:23Daniel 5:23) as opposed to "our Master in Heaven", which would be the translation of the words in the above prayers.
