Abs issue

I have a 2004 Tacoma. Had an issue with corrosion in the wiring blocks for the rear tail lights. Blew some fuses so I fixed the wires on the tail lights. Replaced fuses and all hell broke loose. Abs and check engine light came on. Truck would barely turn over but it did start. Battery said it was good but I put a new battery in and no more starting issues. Took it to my local mechanic to check codes. It says no communication with abs. Check fuses all good. Now as I'm driving home at night with lights on after about 25 minutes all lights, I mean all lights go dark. Turn switch off and on, lights come back on for 20 to 25 minutes then go dark again. Repeat. Not sure where to even start to diagnose the issue.
