This problem only happens to me when I take tight left turns with less than 3/4s tank. No problems when fuel is above 3/4s.

I'm gonna replace the fuel filter and see if it solves the problem, stay tuned.

youre going to be replacing the whole fuel pump then...the filters on the pump...just giving you a heads up

it could be...the fuel pump is electrical and any type of electrical issue associated with the pump could cause it to go out(i.e. a short)

At 10:58 you can hear the cut.

were you in VTEC range coming out of that corner at 10:58 ?, it sounds like the car is dropping out of VTEC range. Engaging VTEC has a big effect on oil flow so if you had oil starvation it could have caused it to drop out of VTEC. Also was it happening in the corner just before the one you took at 10:58, it seemed like the chassis was becoming unbalanced in that corner which can happen if VTEC is engaged and disengaged (though it could have been driver error as well). If you weren't in VTEC range then I'd say that it's fuel starvation as a loss of oil wouldn't cause that effect unless you were in VTEC range.

Hey, the guy driving has never driven anything RWD before, so that would explain what looks like the car is unbalanced, in reality he just turned too tightly and floored the throttle too soon.
Yes, the car was in VTEC range when the power cut occured, however my oil levels were fine ( I checked many times throughout the day), unless the problem lies with the sump.

But its removable, so no you don't need to replace the pump. Just a heads up

Hard to say if it can be a drop in oil pressure with a full sump of oil, or a drop in fuel pressure with a full tank of fuel ?. Neither should be happening.

You almost need to discern if it felt like the car was simply having a drop in power and then re-gaining power, which would happen with an oil pressue issue disconnecting and re-engaging VTEC - the car would still be powering forward just with less force. Or if the engine felt like it was completely dying - like a stall condition - where the car was not powering forward due to engine cut, which would then be a fuel problem. I think that is important to figure out, and they are two different sensations.

After the hesitation the car would pull just as hard as if it didn't cut out, i didn't notice slower acceleration than normal. It was simply revving to 5000, 6000, then just before about 7000 it would stop for a second and keep revving as if nothing happened.
So odd.
