Your phone may just be rejecting the kernel.
If it's a refurb unit - typically replacements are - then that's probably the issue right there as LG did something to them that MtMichaelson has yet to figure out...if he's even alive anymore that is...haven't seen him here since he posted the ROM.
If you're not on a refurb unit then it may be the clock settings that are being rejected.
If it's not the settings (regardless of your clock) then it may be the clock's default 1.5 and your processor unfortunately just can't handle it.
Could also be faulty memory on the phone, faulty processor, faulty hardware elsewhere, bad wiring, overheating, shorting, water damage etc. etc. etc.
