My '99 Sunfire is finally starting to act stupid after 195k miles of great service. I was hoping you guys could help with some ideas so I'll have a better idea of what to look for this weekend.

1st problem: Last week, my serpentine belt broke, only on one edge. Only broke one of the ribs. The think looked like it was dry rotted and a figured that was the problem so I went to Autozone and replaced the thing sitting in the parking lot, only to have it break on me again last night in the same manner and on the same side!

2nd problem: Lately my car has been doing some really stupid stuff. It gives me problems starting on occasion but other times will start up perfect. One night, all of the lights dimmed and the motor went down to about 400rpm. As quickly as it dropped, it came back and I didn't have another problem out of it that night. Another time the car died on me completely just after starting without any obvious reasons. Started right back up when I tried it. Last night, while driving down the road, I had a complete blackout for a second! Everything went off and came back on! Then, my ABS system acted like it went out, even though the brakes were working fine. After turning my car off and restarting, the ABS lights went out, but the radio lost all of it's presets, time, and the last station it was on before shutting the car off, like someone had killed power to it! I've had a couple of people tell me they thought this could be the ECU. Any ideas?
