hey there ,i own a 2000 4x4 blazer,4.3, and im having those same exact problems.have you resolved yours yet ? if so what was wrong,any help would be apreciated thanx

 

There could be a loose ground wire somewhere. I had a similar problem with my '88 s10 blazer and there was a ground strap under the dash on the drivers side that was loose. I'm not saying that is going to fix your problem but it's worth having a look.
