02 Accord Coupe V6 EX Stalling
Hi, my 2002 Accord V6 EX has recently started stalling out, It tends to do it more on inclines and long,sharp turns, seems to do it more on days with higher humidity out.
I'll go to give it some gas and I'll feel the pedal go to far and then notice I'm just loosing speed and rev'ing up a little and then the engine dies and I have a few seconds to dump in in neutral, and 5-10 seconds to get it to the side of the road before it completely powers off on me. Every single time is starts right back up and strong at that. No grinding sounds or anything like that.
First off,I'm pretty sure its not the ignition switch. I've dealt many an hours troubleshooting an ignition switch and cylinder and no fails when jigging the key.
I've checked my air filter and that and the passage ways are all clean. Suppose I could open it back up and spray some Mass Air Flow cleaner in there.
I've had the car for 5 months now and its only started doing this the last 6 weeks.
I plan on checking my spark plugs for oil and there general age tomorrow, but if my valve covers leaking, it would be really minor since the heads are really clean.
My power steering pressure return house is leaking around the joint and it leaks down onto my accessory belt, but not enough to get it to squeak. It is however getting power steering fluid on what looks to be an engine/Power steering pump ground, could that be an issue?
I also noticed today that the main exposed ground that you see if you track the batteries negative cable is about half way corroded away.
Could be a crankshaft sensor, if It comes to it, Ill look into checking its electrical readings, Could be the main relay, I had a 98 that had a bad relay, but when that would stall on me it would typically take hours to be able to restart so I'm not thinking that. I know the ERG valve was replaced a few years ago, and don't have a rough idle at all or have racing RPM's that are commonly associated with those failures either.
Besides testing the fuel pressure,I'm not to sure where else to check, and would appreciate any help!
Thanks.
Can provide any pictures needed
OHHH on a side note, Is this transmission a CVT?

UPDATE:10/4/18
So far I replaced(made) a new negative cable a few weeks ago and it still stalled. I made a few mistakes the next weekend. I cleaned up my trunk so nothing was on the fuel pump area, ran seafoam from the engine and gas tank, started running high octane gas through it, added some trans additive, taking apart the main relay and re-soldering all of the contacts and tracing them with buss wire, and cleaning out of throttle body.
That was 2 weeks ago and it's been running pretty good, I've put like 120 miles on it and it hasn't stalled or feel like it was going power off. Since I did it all in one day I can't say what, if any of it, has at least temporarily correct the problem.
The throttle body was pretty damn dirty, I couldn't see the gap around the valve with the carbon deposits on it. I also didn't have enough seafoam to properly do it, had like 1/2 a bottle and need like 3/4 but plan on doing my oil soon so I plan on doing another round and doing the vacuum line cleaning. I didn't get any of that black smoke so maybe she wasn't that dirty.
I did find service records for it going back 8 years from the last owner over the weekend and the main relay was replaced in 2014 and the fuel pump was replaced in 2015 so they "should" be okay. I did notice it looked like they used a generic fuel pump if thats a thing because the wires going to the pump were spliced together and electrical taped. I'm the kinda guy who carries more tools in my trunk then I do in my house and I could have been shorting those out for a split second with the box of sockets and wrenches sitting directly on top of it!
I did buy an idle air valve control gasket so I could clean that but It wasn't idling rough or have other symptoms of them being cleaned so I might wait of on that.
But is there anything other things I should check and clean up that I haven't already?
Thanks guys!

Check your ignition. I had my 98 Accord coupe V6 stalling on freeway and middle traffic I would put it in neutral and try starting as I rolled down the freeway out traffic . Found my ignition was burned out. Replaced never did it again. Honda had a recall on the issue years ago .
