It happens while driving as well. Not to mention when I shift to drive. Sometimes the windows will stop working...I think somehow it is all tied together. I have had the truck (95 Suburban) for almost 3 years and it has always done it. I just replaced the alternator last week and it is still doing it. I really appreciate your time.
If it is a short, there should be fuses blowing. Having a bad ground will definately cause this type of behavior. I had problems just like this and more with my 93 a short while back, and there were several grounds that had been taken loose to replace te engine, but had never been put back.
I looked and looked and looked for months before I finally took it to the dealer and paid them 150 bux to track down and fix the problem. Several ground wires later, all is fine!
