Computer error

I have a 2003 ml 500. Computer Error Flashes and thecheck engine light came on and car stopped running. The car will turn over but run for about 20 sec then shutsdown. After one hours it started up and runs fine for another 30 mins then cutoff again. Any got a clue ?

I have the same exact problem, any help with this is greatly appreciated. Basically with mine, it turns off while slowing down or stopping and flashes computer error. I'm able to turn it on again after about five minutes, but it seems to turn off after driving for about 15 - 30 minutes. After it turns back on, the Check Engine light is lit for the rest of the drive, but will eventually disappear.
