Lexus Es 300 Stalling

[bamaskater11]

It is a 2000 model and I was driving it on the Highway, then came to a complete stop and about 10 seconds later (while still stopped), my RPM's start to rev up and down and then it stalls. I cannot figure a way to fix this without taking it in to a shop. Any suggestions?
