It's getting to hot probably losing the additives in the antifreeze causing it to boil . I would suggest having the coolant system flushed

Head gasket failure, exhaust gas exiting out into the cooling system, Replace head gasket, get it pressure checked for cracks and if good have it resurfaced and use new gaskets.
