gotta find the cause, before you can fix it.

5min = time to get up to operating temp.
would be good to have accurate coolant temp and I would test for gasses in the coolant.

The 2 most common cause for this is either you have a bad coolant pressure cap or a cracked coolant bottle which, once they start cracking, don't repair well.
Has your engine overheated at all recently?
