Car stalls while driving on highway

Engine Performance problem 6 cyl Front Wheel Drive Automatic 105000 miles

I have been having issues with my 2000 Honda Accord stalling usually in stop and go traffic, or recently while on the highway at 70mph. I notice the engine sluggish and the throttle unresponsive. This is not an electrical problem because the engine remains on, only I cannot get any response when I step on the gas. There is currently a recall on the ignition switch, which I am ineligible for. This problem happens randomly.

Weirdly this happens most when there is luggage in the trunk or the trunk is over loaded. Is there a sensor in the trunk somewhere that affects the fuel pump? Usually happens after the car has been running for a while.

No check engine lights, diagnostic showed nothing wrong.

I have been researching, and found similar problems related to ignition switch, or main fuel relay, or fuel pump.

Any help would be appreciated, I am taking it in for service tomorrow and going to start with the ignition switch, and see what he says. I trust the mechanic but would like to pin point the problem to save some money.

Thanks for you help in advance.

Hi
Don't think ignition switch is at fault. More inclined to suspect fuel pump. When car does this will it just snap back or do you have to stop and restart?
Let me know

No well if I am starting the car it will start, then idle down sputter and die, I then have to release pressure from gas tank (dont ask why it helps) then wait a while and eventually it will start up again.

The other day I was on the highway, and the gas was just not responding and I had to coast from 70mph down to about 15 then it stalled, and I did the same trick and got it going again.

The car is very sluggish during all of this while driving. I thought it was the ignition switch or coil since there is a recall. But now I think it could be the main relay that feeds to the fuel pump.

The car is in the shop as of this morning, so any advice I can call the mechanic and tell them to check.

Of course I drove it last night, nothing in the trunk just myself and the performance and stalling was fine. Like I said its intermittent and doesnt happen all the time which is a pain in the ass.

Thanks for your help, it is greatly appreciated.
