98 F-150 4x4 Blows heat for a minute then cold air

I just purchased a 98 F-150 4x4. The heat is acting up. It blows hot for a few seconds then the air goes cold.
I have been told that the hoses are hot coming in (my mechanic hasn't had a chance to look at it anymore than that).
Any ideas would be appreciated. Thanks

Will get that checked, thanks. I am thinking air lock in coolant or heat core plugged. Am going to try to get a good coolant flush/back flush.
