2004 Chevrolet Malibu Q&A

2004 Chevrolet Malibu Question: My fuel gauge works when you crank the car up and then after about 30 seconds

This just started yesterday after I filled up my car and went to the store and when I came out and cranked the car up then the gauge went down to empty, what could cause this problem ? -
