Default check engine light only comes on in the afternoon

Every day I leave for work no check engine light, when I start it up to drive home I get a code 27 on injector 5. I reset the computer with my scanner but I comes right back on again. I swapped out the injector and that fixed it for about a week but now it started come on again only in the afternoon. Any ideas why? Please help

Possibly a bad wiring problem or a coolant temp sensor. Or low fuel pressure.
