My 03 suburban was running great! Than all the sudden pulled up to a stop sign an it died but started right back up an took off! But all lights came on. On the dash buddy said it was either alternator or battery but checked both of them an they are fine! Googled an it showed a black an yellow wire connected to the back,passenger side of motor it was brokw but fixed it an still dies and idles rough! An as it sits there the rpm gauge moves and sometimes the battery gauge goes from 14 to 12! An the ac went from blowing cold air to hot! Like ive said ive googled and googled its says brake control module, fuel filter/pump but haven't tested pressure yet please and thank you for your help
