Glitches then failure

[glib]

Four times on my ride this morning I felt the electrical system glitch--that is, turn off for just an instant. As I was pulling into my garage I felt it again but this time I was looking at the gauge cluster and it went out completely for that same instant--so it wasn't just the ignition. Then the bike went "dead." I pushed it in and tried the start button but there was no power. Then it seemed to come back on but when I tried to start it, it went out again--as if there was a tiny charge and then none. I checked the battery and it was 13.00 volts. Started the bike and it went to 14.25 and changed little with rpm--14.40 tops. Key off and it went down to 13.7 and slowly dropped from there until I turned off the key. Put the seat back on and it started right up again. I also noticed that my headlight was out. I believe it was working before today.

Any ideas what this could be or where to start looking?

Never mind. Just an obvious loose connection.
