My 2001 Impala LS w/ aprox 122K miles recently began to stop when I'm driving it. No sputter or other warning - almost like switching the key off. It starts right back up after coming to a stop and putting it into Park. It has done it several times in the last week, however, not at the mechanic's where it spent today. I thought maybe bad gas and tried a gas additive, but that wasn't the solution. I can't go on like this.

Anyone got a clue? In my opinion it a fuel delivery problem (filter - pump?) and no, I don't know then the filter was last replaced.

Thanks in advance for your assistance folks

No codes - nothing.... We're going the Ignition Control Module route which according to the tech wouldn't leave a code unless it totally failed. From the internet feedback it does seem to be the most likely cause of the problem. A bad Crank Sensor would have left a code so it was removed from suspicion. The bizarre thing (to me at least) is that it has run fine for them for two different days, but failed when I drive it. Keep your fingers crossed for me.

The tech told me they scanned everything and came up w/o any codes. I didn't know enough to ask if both of those areas were scanned, but I've got it back w/ the new module to see if that cures the problem. I'll report back w/ the results.

I got home from the garage yesterday just fine, however, during a brief trip of about three miles this morning it quit three times! I limped home and will be heading back to the garage Monday morning. At least the Ignition Module has been eliminated.
