i had this problem once when i changed my batteries after the rechargables went flat. i grabbed some alkaline batteries from my bag they were maybe 6 months old but unused i put them in my detector and it kept switching itself off every now and again took batteries out and notice the batteries had some slight surface corrosion on them rubbed the ends of the batteries on my jeans and problem sorted. With low voltage a small amount of corrosion can cause problems.
