2003 Chevy Taho problem?

-Hello recently i've been having problems with my 2003 chevy tahoe.Now the problem is when i start the car everything goes fine until i hit a traffic light.At the stop light the car tries to turn off and the PRND lights start flickering on and off as if the car is trying hard to stay on.If i stay long at the stop,the car usually turn off and its pretty hard to turn it back on.So i was wondering what the problem is and how do i fix it?Thanks.that sounds a little odd to say the least, here is my suggestion go to carcomplaints.com and click on the manufacturers name to the left in blue letters on the home page. click into the page and scroll down to click on the model and year, read some of the complaints from that year and see if they sound similar there may also be a link or some information on how to fix the problem, through either the recall information or the TSB (Technical Service Bulletins) good luck.

I did check carcomplaints, and sure enough there were plenty of complaints about these vehicles and

5 had similar problems and it seems the dealers like to guess things like dirty fuel injection, charge two hundred to clean it and it does not fix the problem, and replacing fuel injection was an expensive option there seem to be slap on some expensive parts and see what happens which ain't right. I also read this morning about an 03 suburban that had a problem with the engine going into that limp home mode took it to his own mechanic who replaced the ground on the back of the engine block and cured his hard to start problem and his limp home mode popping up . For what its worth, giving the the vehicle and new ground from the block, and cleaning the contact points thoroughly makes sense to me especially if its a wire its ten years old now. my suggestion is replace that. and hope like heck it cures the problem, because replacing some high dollar parts like the ecu, the fuel injection is next on the list.
