    Been having on and off issues with truck stuttering and stalling at random times. It doesn’t happen all the time. It may go 2-3 weeks without any problems then all of a sudden it will stall out and crank right back up like nothing ever happened. I recently had it stall out twice while making a left turn. It is very inconsistent which makes it hard to troubleshoot. I was thinking fuel pump and or filter issue but with how inconsistent and times in between it happens makes me think it’s something else. I would think if clogged fuel filter I would constantly have problems. I have changed coils, plugs, and wires. Also pulled the throttle body the most recent and cleaned which after I did that it stayed running fine for over a month. Mass air flow has been cleaned also. I don’t know where to go from here since the issue doesn’t happen all the time. There is no check engine light showing up which also doesn’t help. Any suggestions are greatly appreciated.

    Internet guess is a crankshaft position sensor. Go to Auto zone / o reillys and see if there are any pending codes.

    I have a very similar issue going on with my truck right now. Same engine and same inconsistency.

    You can look at the thread I posted yesterday to see all the parts I’ve tried, one of those could work for you.
