Not too sure.

When you use my for the first time each day we'll get down the road abit and then the car loses power and then stops. After sitting there for awhile we can then start it up and it'll go sweet for the rest of the day. On top of that the temp gauge rises to the halfway mark pretty fast. Any suggestions on what might be the problem? I've had people tell me that the radiator may be blocked, the themostat might need to be changed and the head gasket may need replacing.
