15min from first crank of a cold engine is a short amount of time to be over heating already. As stated above use only OEM Mazda T-stats anything ells can cause improper cooling and possibly overheating.
This is a quick amount of time to over over heat so IMO I would look at air in the cooling system and a clogged RAD as well as stated blown coolant seals. Check using a coolant pressure tester or by looking for bubbles in the upper hose if S4 and the lower if S5. This being mentioned b/c if your coolant seals are gone the motor will heat the water up allot faster as well allowing air into the system.

Depending on where the seals are blown, the motor will consume coolant, and the reservoir will run dry eventually, but the compression side or the exhaust side of the coolant seal (blown) will allow air bleeding off into the system, making it boil over incessantly without burning any of it.
I'm curious about what his reservoir is doing during his overheat. If the level rises just above norm from the temperature, or totally boils over non-stop, or is slowing losing (eating) coolant.
