Would a bad/intermittent ground only occur at specific temperatures?
I thought the same thing, but the fact is that it occurs almost exclusively at 120-140 degrees on the temp gauge after sitting overnight. It ran really well today, smooth idle, good throttle response, etc.
Well, I'm going to look at the fuel pump circuit schematic and dwell on this for a while...might have a beer too.

thanks...
