2009 Electrical Problems

[jbchevy1075]

I am having problems with my electrical system from time to time. The issues are intermittent and don't always happen at the same time. While driving the sometimes the Stabilitrak will turn on and off, other times the door locks will lock and unlock, eventually the motor will start to slightly misfire, and eventually wont restart after shut down. After about 5 or 10 min after shut down it will start again and the cycle starts over. This only happens once every 2-3 weeks. As you can imagine this is very annoying for my wife and kids in the 100 degree Texas heat. There is no check engine light that comes on during or after the problem has occurred, codes have been read with nothing found, and battery terminals are cleaned and tight. I am pretty mechanically inclined so ANY advise would be helpful as I don't want/ can't take it to the mechanic to get worked on, just don't have the money. Any ideas?!?! :help:
Thanks in advance!

Use 0 or 2 gauge ground wire from the body to the engine then from the battery to the body. I had the same issue. This solved it
