2006 Dodge Magnum 2.7

My 2006 Dodge Magnum Has Blown My Radiator
Hose Off 3 Times Within A Year!! First Time It Was
The Bottom Hose The Next 2 Times It Was The
Top Hose!! The First 2 Times I Put Hose Back On &
Water In It & Had No Problem. BUT Yesterday I was
In A Atm Drive thru & Heard A Knocking Sound &
Admeidilty Turned The Car Off & Coasted To A
Parking Spot. I Lifted The Hood And The Radiator
Hose Was Off Again At The Top. I Put It Back On &
Put Water In It & It Wouldn't Stay Running, It Would
Turn Over Then Cut Off. So I Looked Under Hood
Agian & Took The Cap Off Of The Resovoir & Water
Came Boiling Out & Was Very Hot!! Seemed Like It
Had A lot Of Pressure In It So I Tried Starting It
Again & It Started & Stayed Running So I Drove
Avout A Mile & The Temperature Gage Started
Shooting Up So I pulled Over & Had It Towed
Home.  It will still run & there isn't any coolant in
my oil so I don't believe that I've cracked a head.
Please help!!!???? Could it be the thermostat or the
water pump?????
