So much for that theory that the no start is correlated . I wa s hoping it was a poor connection in the ignition switch.

I'm having it towed home and then I'll work on the ground points

SUre seems like an intermittent connection somewhere. My first guess is in the ignition switch. Next time it fails, remove the key and reinsert. wiggle it around a bit while trying to crank. see if you can get that connection to......connect. Entirely possible the switch connections have a little carbon build up or have worn some.
You could go overboard and remove the column trim and tap it gently with a hammer while they key is in ACC with no chimes. Do some more testing to see if the chimes and no start are correlated.
Could also be loose connection in the fuse box. Had that happen to me once. Maddening.

I removed the key, reinserted, wiggled the key... Nothing.
As soon as the Colorado was off loaded from the tow truck it started right up. I wanted to take a sledge hammer to it.

That stinks! Sure smells like a loose contact somewhere. Before the sledge, check starter connections. Wiggle fuses. Heck wiggle fuse box. At least it's home now, but I very much feel your pain.

watched a couple of videos and got some insight into my problem. I took the ground points box on the driver's side apart (not easy).... apparently that controls ignition.
I was reluctant to cut those wires and put ring terminals on. I cleaned the connections as best I could and put an extra ground wire from the bolt to the battery ground. I'll take it out tomorrow to see if anything changes.

A normal trip to the store with my Colorado turns into an adventure but... no starting problems.
I managed to return home w/o a tow truck and multiple start ups thru out the day were trouble free.
