Thank you everyone for the input! I hooked the phone lines into my blocks today, and sure enough, intermittent problems where I doubled up! I am using a "split" block, with my extensions on my left and phone line on the right, using bridge clips to enable a line to each extension. I doubled up on the right side, at the top of each block (There are 5 blocks total, about 25 4 pair extensions, and 4 phone lines going to each block). On Monday I will have to reconfigure these so that we are not doubled up. I will try to get some pictures of this.

Flat blade screwdriver in a 110 block!? Ugh, should be a lot of service calls in his future! Punchdown tools stay in the Phone/Data bag no matter what. You can do almost everything you need with a punch, 10-in-1 screwdriver, and cable scissors.
