Bought an '05 Vibe in May and really like it. Once about a month ago and again last evening, I got in to start it, AC running and the fan speed nearly full and it never turned over before the whole electrical system shut down. The first time it happened, power came back after 15 to 20 minutes. Last night, it took several hours. I have had both alternator and battery checked and they are good. Don't know what to check next. Now it is 8/7. Got it started after -3 hours of sitting the first night and it started right up yesterday morning so I made a trip or two.l Went out this morning and nothing. Dash lights and buzzers but it would not even click to start. Went back out an hour or so later and it started but there was clicking noise before it started. When the system goes out, my radio clock has to be reset when it all comes back. It could be the starter or solenoid. A local parts house sells both for $10 more than just the solenoid which must be ordered. The complete unit is in stock. Am now also wondering about the ignition switch but have no idea how to check it.
