Will try to get a new fuel pump before next track day.
Hopefully this is it. Don't wanna swap out plugs for each track day. lol

I still have the prior plugs (6k miles), will try to put it in later and see how it goes.

Thanks for the advice guys, appreciated.

do you have a cat on?
Like others have said man--this isnt a sparkplug issue. Really. The engine cooling between the time it takes to replace the plugs is probably the reason it runs better afterward?

you could hook up a pressure gauge to the fuel line before just throwing a $300 pump at it. as in i meant doing the diagnostic on the pump to rule it out or verify that you are losing pressure when the stalling issues crop up.

Oh no~~~

Totally possible.

My pump was showing sigh of wearing, but I wasn't sure.
(It'll choke a bit before warm up)
It's an 8 years old pump that have seen high mph and some tract events, i guess it's about time.
Deatschwerks DW200 is on my list.

i rarely suggest reusing the pump housing, the outlets tend to crack on the older 8's which could in fact be your problem.

a quick inspection of the top of the tank via the pump inspection cover may reveal an already cracked pump housing outlet. (wet, failed. dry, it's fine for now)

Lalalove there is so much more information we would need than that.

and making your own thread might get you better and more answers, as well as reading the FAQ threads. most common reason for no starts is "fuel flooding" from an extremely short previous trip.
