2002 Monte HELP!

[bluf1sh]

Im sure this question has been asked but i searched the first 15 pages on nothing really helped me out so...

I own a 2002 monte carlo ss and in recent months it decides to die. I could be driving at any speed; sitting at a red light; and the car will give me a battery sign in the command window and just die. Sometimes ill have to wait for 10 minutes in order for it to start again, but other times it will start right away. I took it in and the dealer found no codes, only that the car wasnt getting up to temperature and had the temp thing replaced (sorry dont know alot about cars) also the fuel pressure is good. Has 64,000 miles son it.

If anyone could help me out i would appreciate it.

It could be the crankshaft position sensor. It will cause those problems and rarely sends a code to the computer. It is very common on gm v6's.
