00 Tahoe won't stay running

Sometimes when you run it out of gas it burns up the fuel pump. The fuel going though it cools the pump. Most people don't run out of fuel and accept fate and look for gas, they try starting it multiple times before establishing they are going to have to get gas. All that burns up the pump, it doesn't take much and every time the key is turned the pump runs. It's also a good idea to change the fuel filter if this is your issue.

Thanks
