Try running an Internal Accounting Review -- there are 2 checks there that may help:   1) It checks for Purchases or Bills that do not credit an AP account; 2) It checks for Transactions that debit and credit the same general ledger account

I did figure out a way to narrow my search.  I wasn't even thinking about the Trial Balance and the fact that it can be ran by date vs. period so running it and the A/P Aging for the same dates I'm able to pinpoint the exact day that the error occurred.  It's not a perfect solution, still very time consuming, but it is better than nothing at this point.  Thanks!
