2011 Chevy Silverado - Electrical Issue - Engine shut off and on while driving

[bradlabs12]

any help would be great.

Over the past couple of weeks my 2011 Chevy Silverado has been acting crazy.

I will be driving along  and the truck will have the following happen in order 

1. the locks will unlock 
2. the engine will lose power
3. the check engine light comes on 
4. the engine will regain power
5. the check engine light will go off
6. the locks will relock

This happening within the time you could snap your fingers ....and then... the truck acts as nothing has happened.

I have had it to the dealership twice...

• Once to fix AC and try to determine the issue --- Could not find anything within the codes or recreate it 
• Again to look at this issue -- Could not find anything within the codes or recreate

 

I have trying to replace the battery in not key fob -- did not solve it.

 

Any ideas would be a huge help!!

because it is electrical, its nearly impossible to diagnose the problem.  The solution might be as simple as cleaning your battery terminals or the connections to the charging system.  It could be a faulty wire in a number of places as well.  It could be an issue with the ECM, or BCM.  Could be your ignition wires, or wires to and from any one of these places.  I would start with your connections for battery and alternator and go from there.  Get your alternator checked out, as well as your battery tested too.
