Need Advice on A/C Problem

My A/ C is acting up and I do not know what to do about it. Most of the time it works just fine. On a cool day it will put out 38-40 degrees. On a hot day it puts out about 45 degrees. So I think the refrigeration system is OK.

However, when my truck gets real hot, sometimes the A/C temperature goes up by 15-20 degrees. Also the air flow from the registers is reduced by about a third. So I think the problem is in the venting system.

The problem being somewhat intermittent makes it more difficult to troubleshoot. I do not have any idea of what to check.

Any help will be appreciated.
