Possibly your overflow bottle is not working right. Plugged up somehere? Water expands into bottle and then draws back into radiator. If it cant draw back it will collapse hoses from suction. And make sure your system is full and your radiator cap is good. You might try a new cap first. And your upper radiator hose should have an internal wire spring that keeps it from collapsing.
