Yes, as a matter of fact, I have seen an ECU fail in a GM car. Specifically a '96 Suburban. The truck would stall, and it would take about 25-60 minutes for it to ever start back up. But she never had to be towed home. My dad drove it like that for 2 years. Only about 6 months ago did he ever replace it, and last I heard, he was still having problems with it, like a 300rpm idle, and a 1500rpm WOT. I wonder how smooth a 300rpm idle would be.. my whole car shakes at 800rpm.. although it is the 6.5L diesel.. and diesels are much different than gas engines.
Either way, I do see what you are talking about with the ECU failure. My bad that I didn't realize it. I'm going to move my opinion to ECU failure.

Success! My girl runs again!
And all it took was a little gas in the tank!
I discovered the tough way that the gas gauge doesn't go below that section between 1/2 and 1/4, let alone set off the 3 ding warning light saying the tank is empty. We put 5 gallons of gas in, and she started right up. When I filled the tank up, it went to F, but when it wouldn't start, it wasn't near E. Does this sound familiar to anyone?
The fuel filter is old, and I didn't check the fuel pressure, but it wouldn't surprise me to find problems there down the road. I'll check the FPR vacuum lines for leaks too. I still think there'* a fuel problem beyond a faulty gauge.
A tune up with new plugs, wires (Delco, nothing fancy yet) and a good throttle body cleaning have her running better, and so far she'* kicked into fast idle every time. No sputters, stalls, and the engine is running smoother too.
I'll post again if anything new pops up.....

BTW,
Glad you got her running and it was cheap though a bit embarrassing. I've always told my daughters to consider 1/4 tank as empty. Kind of like aviation, you always want to have a reserve for the unexpected.
