why wont my 1999 CHEVY TAHOE start back up, it was running fine,and the battery is charged
The problem could be that you have a faulty fuel pump. There are also other things that you need to look at like the spark plugs, the fuse or the timing is not correct. Contact a mechanic for more troubleshooting options.
maybe check battery connections or your starter may have went out
Did you run out of gas?
