Good Afternoon,

My 2000 Accord EX with the 6 cylinder engine has 196k on it. There are not any check engine lights. It runs great for an old Honda. There is one weird issue. If I drive it on the interstate for 30 minutes or so at 70 to 80 MPH and then stop for about 30 minutes, when I come back to the car to start it, it will try to start but then stall. If I wait another 30 minutes, it will start right up and run as normal. I was originally told that it might be a bad ground. I pulled the battery and cleaned the ground going to the engine block. It was so bad that I was surprised that it worked at all. I also cleaned the ground going to the frame by the radiator. It seems to be better but still will not start from time to time. I have this issue maybe 1 time per month. Does anyone have any other suggestions about this issue? Thank you.
