Driving back on a road trip in a 2018 expedition max with 83k miles on it, and went to pass someone and the engine lost power (would shift up, went "limp") the check engine light began flashing. Pulled over, put in park and light completely went off. Hasn't happened again, and we've been excelerating perfectly smooth. Transmission was replaced about 2500 miles ago also and just had it in for the cam phaser CSP. Thanks for any insight!
