Hate to say it but it sounds like the dreaded unintended acceleration that Toyota and most members of this forum deny exists.
Do you have the Smart Stop Technology installed? It's a free upgrade available from your dealer.
Do you have a weak battery? UA has happened to 9 members of this forum and the common denominator seems to be a weak battery.
Is the floor mat interfering with the accelerator pedal?
Be prepared to be attacked as a bad driver or having your foot on the accelerator instead of the brake.:smile
