the issue is more than likely with one of the 26 e-commerce components or the fact that you have 26 instances of a complex component on different pages. I do not believe that it was envisioned anyone would use that many e-commerce components on a single site.
You can start taking them off one at a time until you find the one that is the issue but if you are going to go through this much work you might as well just create a manual storefront which will be a LOT easier to maintain.
You may want to contact your web host to see if they provide any type of MySQL based e-commerce software with your web hosting. I offer os commerce, zend cart and cubeCart, your host may offer something like this with your hosting plan.
