My 2003 Acura MDX recently began experiencing an engine problem that can be characterized by normal operation for a few miles and then sputtering until the engine begins to miss and will not go at all and acts as if it is in neutral. This same pattern is repeated if the vehicle is turned off and then the same problem occurs again. Do you have any ideas as to what may be wrong?

Not enough information! To properly diagnose this your vehicles problems you would need to take it to a Honda mechanic and have the problems you describe act up for them so they would know what to test.

It's very possible that there is a problem with your transmission which is causing the vehicle to stall. Since you mentioned that it feels like it's in neutral after the stalling, I would have this checked first. I believe that you have a 7 year 100,000 mile warranty on this transmission and it may cover any problems you're experiencing.
I found a site that talks all about the MDX, good and bad. Take a look and see if this helps. It would also help if you are getting a check engine light so that they could read it with a scan tool to find out the component that is causing the trouble.

I would probably need some more information to give you a better diagnosis, but I will tell you what I know, and maybe this will help. If the vehicle runs okay until the temperature of the engine increases, I would look at the sensors that are affected by engine temperature, such as the exhaust gas recirculation valve(EGR). This valve is not in use at idle or when the engine is cold. If it is clogged, it will cause a miss and eventually shut the engine down. It will also make it hard to restart the vehicle while it is still hot. It would help to know if you have an engine light on, or if you have access to a scanner, what codes you might be retrieving.
