My car's been M50 swapped for about 12,000 trouble-free miles, but then yesterday out of nowhere after a 200 mile trip it just shut off mid-drive.
Wait thirty seconds or so and it'll fire right back up without issue and run perfectly, then die after about 30-45 seconds. Rinse and repeat.
What's weird is that i'm not getting any codes, idle and power are perfect, and everything else seems normal. When it shuts off, i've still got electrical power, and the CEL stays on, which must mean the main relay is still fine.
CPS is new (12,000 miles old, dropped it in at the start of my swap)
Fuel pump relay replaced - same problem.
Fuel pump primes when the key is turned to "on" after the car's been sitting for a few minutes
It doesn't die like it's running out of fuel (no sputter or anything), but just like to pulled the key out. If the pump was dying, i'd get a sputter, right?
Anyhow, i'm stumped at this point, and am just looking for any ideas!
