Hey, i have a problem with my 2003 GMC sierra 1500 4.8L v8. When i try and start it sometimes it wont start. I put the key in accessory mode right before i crank the engine and all my gauges start moving like normal but when i try and turn the engine on they freeze and the whole truck loses power. Everything just dies and it feels like i have no battery, everything just turns off. I have to get out and disconnect the battery then reconnect it and it will start just fine. Any ideas?
