2001 Pontiac Montana sporadically stalling
 

I have a 2001 Montana with 135,000 miles that was skipping when you showered down on the accelerator and flashing the check engine light. Yesterday i changed the spark plugs and wires which had never been changed before and that problem is fixed now. It runs perfect now, no skipping and its smooth as a sewing machine.

But we were driving down the road last night and we were coming up to a red light and the engine just shuts off. I look down at the guages and everything looks normal except the RPM guage drops to zero and the battery indicator light appears. It doesn't stumble then shut off, it just shuts off like you turned the key switch off.

We put it in neutral while we were still moving and it fired right up and we kept driving to the movies. It did it again when we were looking for a parking spot. After the movie it didn't do it anymore the rest of the night.

It had done this a few times before i changed the plugs and wires but its so sporadic i dont even know were to start. I am pretty sure the two problems were not related at all because it runs so good now and the the check engine lights does not flash any more. I also cant get it to throw a code for the stalling.

I think I would start by checking the fuel pressure at the schraeder valve to decide if the fuel pump should be replaced or not.
