I have a 2003 or 2004 Craftsman LT1000 16 OHV with a Briggs and Stratton. The mower starts easily and runs great for about ten minutes then it just dies. It will re-start easily but dies almost immediately. If I let it sit for 20 or more minutes, it will restart and run great for ten minutes or so before it dies again and the whole process starts over. It seems to happen at almost the exact place every time. I have changed the oil, fuel filter, spark plug and air filter and it does the exact same thing. No problems with mower other then battery since I bought it new. Does anyone have any suggestions??
