Curious if anyone here has any experience with an odd stalling issue. My friend's 2014 has been randomly dieing while going down the road. No fault codes stored and it restarts everytime without issue. Lexus put in a new alternator and battery but it has continued to stall after. Fuel pump was replaced about a year and a half ago under recall. This truck has had a non-disclosed engine replacement prior to purchasing, Lexus noticed it while putting in the alternator. Drive and runs normally otherwise. Any ideas?
