I have a 95 Fleetwood. If cooled over the night, I can crank it like nothing is wrong. It will run for about 20 minutes, then it just dies (cuts off). I cannot crank it back no matter what. After about an hour or two of cooling then I crank it back but will stay on about 5 minutes then and turn right back off again. I changed fuel filter to see if something to do with fuel or anything. Yet problem still exists. Anyone have any idea what could be the cause of this? It acts like it gets hot and has its own kill switch. Also no dashboard lights light up to indicate anything wrong when first cranked to when it cuts off on its own. Thanks.
