As I attempted to speed up in traffic, I heard a noise and the vehicle suddenly slowed down. I was able to get it off the highway on to a side road. Once there, it would not start. On closer inspection, I saw that the belt had come apart and off the pulley's. I had the van towed to my home and subsequently, fixed/replaced the belt. Since that time, I began to hear a low knocking, more so when I turned on the air conditioning. When it became louder on all gears and while parked, I took it to holler drivers mart, in winter park, FL. On 01/19/2012, I was told that the flywheel had sheared around the area where it was bolted onto the transmission and connected to the engine. It also had fractures in and around the same area of the shearing. Tech informed me that I had caught the problem before a serious incident may have occurred. I have the fly wheel and will send photos. Consumer sent in photos. 02/07/12 updated 02/07/12 status update 02/23/12.
