My 94 suburban (half ton, 2WD automatic) developed an electrical problem. I turned the key to start and as it began turning over, everything went dead, even the dash and interior lights and would not come back on after releasing the key from the start position. I moved the shift lever while holding the key in start position and it staretd. Problem recurred next day and restart worked again. Today the moving of the shift lever wouldn't work. WHAT IS YOUR THOUGHT. I checed the battery and it's good and it's terminals are tight and clean. Note: I had a similar occurrance with my 2004 suburban when the starter motor relay hung half way, causing all electrical connections to have no power.
