Phone turns off at 4 mins. with Kitchen ROM

[CMeys]

Every ROM I've built with the Kitchen (any version) even a totally vanilla one including nothing but the basics has caused my phone to turn off after 4 minutes even though I have the power settings not to turn off on either battery or external power. This only happens with ROMs created with a version of the Kitchen. I prefer those ROMs as they are the only ones in which I've been able to get MSCV to work properly.

How can I fix this so the phone stops turning off unless I do it manually?

Thanks.
