Strange problem

Fhjkalfhu

So I have a weird problem arising in my base 09 Z. It's been doing this for about a week now, but whenever I go to start it up, it sorta pauses halfway through and then finishes starting. I noticed it at first it happens after not driving over night, but now it's doing it even when I start it again after an hour or so of not driving. The strange thing is my radio also powers off completely and the outside temp reads in Celsius. I'm guessing it's an electric issue somewhere but I can pinpoint it. The only mods I have are:

K&n typhoon intake, test pipes, full cbe, new headunit, new speakers, and a backup camera.

I did try to search but I honestly have no clue what else to use as keywords other than I've used, or if this is even an engine related issue. I did do an Ecu reset after everything as well.
