Tbi 4.3l with 65k miles
Coolant temp is fine never over 190. Only just started yesterday with temps over 105
The truck will die sometimes when moving over 45 mph and sometimes when sitting at a light so speed and rpm are not related. and then wont start right away but does successfully start back up after 5 minutes or so and seems to run fine. It did this several times to me yesterday.
I initially was thinking it was vapor locking but that really shouldn't happen on a fuel injected setup.
I am guessing icm and have one on order from rockauto. Open to suggestions or ideas though.
I have done some searching and I think this is my most likely culprit.
