Narrative:

While in cruise at FL370; we noticed that that the right fuel valve closed light was illuminated bright. We began to discuss the possible risks and contingency plans as we pulled out the QRH. We contacted the company. The right engine began to roll back and then shortly after; came back to full power. We advised ATC of our situation and began to plan a divert then shortly after the right engine rolled back to idle again. We again advised ATC. We decided that ZZZ was the best option to land as soon as practical. We followed the QRH checklist for engine failure through to the single engine landing checklist. On the ground; we were met by the emergency vehicles that followed us to the FBO. The captain was calm and professional through the whole flight and all procedures were followed in accordance with the company and manufactures recommendations. Great coordination was maintained between all parties involved including the crew; the company and ATC.
