Why is my car stalling while driving?

What is your question?

My 2011 Toyota Camry check engine light and slip indicator light have been on for about 4 days. Suddenly, today, my car is stalling or the engine dies while I am driving! I can turn the key to off, then back on to start and drive, but it dies again after driving some more. What is going on?

What makes this problem better or worse?

slowing down or letting off the gas
