D4 wont acquire signal and boot looing

All of this started with the device droping signal here and there. This progressively got more frequent. Earlier today it started boot looping. I have safestrap 3.11. It will come up on hashcode's aokp, D4 HD and stock but they all do the same thing. Now the device will boot up, stay on for about 2 minutes without acquiring signal then it reboots. I disassembeled the phone to look for any bad connections with no result. I'm out of ideas. Any help would be appreciated.
