Honda5280

Okay, so I have a rather specifically timed issue with my car, it is a Honda Accord EX year 2000. Basically, I drive the car around for about 40 minutes or more and then turn it off. If I want to turn it back on immediately, it will have no problem doing so. However, if I want to turn it on 25-45 minutes after I shut it off, once I start the ignition, the rpm's will fluctuate until they drop down to 0 after about 5 seconds, while the engine shakes, and the car will turn off. If I try turning it on 0-25 or 45-anytime after it will turn on instantly and with no issue. The check engine light will turn on sometimes and the codes say that I have a misfire in all 6 cylinders, but it will eventually turn off. I have taken it to 3 different mechanics, the first changed my starter then said it could possibly be the computer, I've had all the spark plugs changed and recently took it to another mechanic but it continues to do the same thing. Any ideas what it could be?

A misfire on all cylinders can point to a bad crank sensor or it could be caked up with carbon or dirt. I would suggest atleast removing it and seeing how bad it is. You can choose to replace it as well.
