Thanks for your suggestion. I'm not really a mechanic and need some direction as to what is or where is the overvoltage protection relay. Also I forgot to mention that when I first start the car in the morning, like today. I would have to step on the gas 2 or 3 times, then start it. The car would shake and almost stall. I press on the gas and feel some hesitation, as if choking. It eventually stalls. I have to start it 2 or 3 times with the same routine until it the hesitation goes away. I may have multiple problems, but don't know where to start troubleshooting. Replaced fuel filter, but also thinking about fuel pump. I've also read in this forum about possible fuel injectors clogged.
