battery, oil and check engine light are on

So, this morning I started my car and it was driving fine. I made a quick stop, turned my car off and then turned it back on and the battery, oil and check engine light were on and it was driving very slow as if it was about to run out of gas. My car has plenty of gas, it does not need an oil change and I have not had any major problems before with this vehicle. I then turned the vehicle off, turned it back on and the lights went off and it was driving fine. I would just like to note, that I recently drove from Oklahoma City to Searchlight, Nevada (approximately 1,600 miles) and before I left I had everything looked at and they said it was fine. I would also like to note that I am in 120 degree heat.
