2008 Lexus 400h VSC and Hybrid lights came on---

I read over the comments and responses--my issue is a little different-
hopefully someone can guide me the right direction---The same time the
lights came on--when I pushed on the accelerator to go faster it did not
accelerate...but when I pulled over and turned off my engine to call my
husband about the issue and started my vehicle again---the lights came on,
but it did allow me to accelerate....I have my vehicle parked until I can get it
in to be checked--what is causing this....battery....fuses????PLZ HELP!!!
