Thanks everyone. The issue was found and appeared to be the ECM. There were a few wires open and caused a short circuit damaging the ECM. But did not kill it completely. All the wiring around the engins compartment was replaced. ECM was just reprogrammed and my baby runs like new again.

Crankshaft position sensor has been checked and was told functional.

Seems like it could be an ECU/ECM issue. Does anyone know if there is a difference between a V6 and V8 ECU unit, are they interchangeable (Or even an ECM from Tundra/Sequoia etc.)? I just found a local guy selling one for a 2003 4runner V6. Not sure though if it fits V8.

Thanks. That was one of the possibilities that we also considered. But since the truck starts up fine after a cut-off that suspicion was eliminated. The battery is still fine.

Haha, good one :)

Yeah, that's what the guys at the shop doing right now, checking the wiring all around. I considered the fuel flow issue and replaced the fuel pump, it did not fix the problem. And it runs for around 10 minutes on cold start. The issue persists only when the engine is warm. Intake manifold...

Thank you for your quick response BlackWorksInc. I have tried disconnecting the battery for 20-30 mins before. It did not fix the issue. I just hit 200K miles on it. Most of the times engine cuts-off cleanly, and only sometimes it jerks off while on the go. No misfire, no sputtering or stalling...

Hey everyone, This is my very first post. I have an issue wih my 2003 v8 limited 4runner. I couldn't find any info anywhere on the web and decided to post it here. Maybe someone else had this issue before. So, the cold start is ok for about 10 minutes or so, and then engine dies. Stepping on...
