pages stop loading

[Guest]

Hello,

 

I have a problem that is starting to happen alot more often these days. My site basically stops loading in the middle of pages some times. for example when i type my url the header will appear and then just stop loading. the same thing happens when loading a product page.

 

can this be because of server load? or another issue?

 

my site is http://www.astawerks.com if you want to see for yourself

 

thanks
