the problem you are having is not fuel related its ignition switch. The year and model you have were prone to ignition switch failures. The electrical contacts on the switch wear and intermittently lose connection causing random stalling. The car usually starts right back up and as the switch wears more it will get increasingly harder to start.There was a recall on the part through Honda and Acura. You will need to call your local Acura dealer and check to see if the car is eligible for the recall and whether it has already been done. If it has been done, there is a great chance the switch is bad again. Replacing the switch will take care of the issue.
