My check engine light came on in my 2002 Chrysler Town and Country a few months ago. I took the van to a parts store where they determined the code to be a vacuum leak. I have checked all over the motor and have not found a cracked or damaged hose anywhere. The vehicle is starting to act up now. It is hard to start and when it does start it is low on power- tourque. Once it gets going it will act just fine until the next time you start it up after a good cool down.
Any ideas?

It would e interesting to know why they determined the problem to be vacuum leak. Did you get a code for EVAP control, and the assumption was vacuum? As a rule, there are no code definitions for "vacuum leak', only codes that can be interpreted as vacuum leaks. You say it is getting worse. My suggestion is to go back again and get ALL of the codes and write them down.
With the list in hand, refer to a repair manual (Library, or purchase one from the parts store that did you the favor of reading the codes). The manual will identify the descriptions, and recommend a DIAGNOSTIC routine, and based on the results of DIAGNOSIS direct you to the correct repair.
Good Luck

Some hoses might have a small hairline crack you can't see.
This happened to me in a different vehicle. I had to replace almost all the vacum lines (don't worry hoses are cheap.)
Then I had to replace a vaccum canister. (Thats not cheap.)
Try the hoses first.

Check your throttle position sensor (tps) It may take some one with a scan computer to do it. The tps is a cause of all the symptoms you list.
