why my car keeps dieing?????

when i hooked up my intake in my car it worked fine but now sometimes the cars battery sometimes dies for no reason or when im drive and at a stop sign the car just shuts off like the throttle body is not getting enough air i hooked up my stock intake back and does the same thing!
PLEASE HELP ME OUT!!!

Maybe you broke the MAF sensor? are you sure the battery is dead?

like i said in the other thread......check for vaccuum leaks!
