Upon a showing of advantage to the estate, the court, with or without notice, may authorize the personal representative to continue and operate any business of a decedent for the benefit of the decedent’s estate, under such conditions, restrictions, regulations and requirements and for such periods of time not exceeding six months for any one period as the court may determine. No debts incurred or contracts entered into shall involve the estate or the personal representative beyond the assets used in such business immediately prior to the death of the decedent.
