2000 Grand Prix GT Starts and Dies MAF Code Sign In

2000
Pontiac
Grand Prix GT
3.8 V6
90,000 miles

Ok service engine soon light came on. We checked the codes & it had a MAF code. Once we repalced the MAF it starts & runs fine. Then when you get to where you are going it will start and die. So unhook the new MAF sensor & it starts and runs fine. Plug the MAF in again & it starts & dies. Take out the new MAF sensor & replace with the old one it will start run fine & service engine soon light comes on. Got a 2nd MAF sensor that was new. Sane problem will start and then dies. Unhook it runs fine with service engine soon light on.

No other codes are coming up except the MAF. But once replaced it will to start and die.

New fuel filter before this problem as well as new plugs, wires & coils.

Suggestions????

You're going to need a scan tool to analyze the sensor data to look for something out of parameter.
