heres what happened.
took my gn out for a cruise today, alot of highway, then through town, all is good running strong all gages reading good.
now just as i get into drive at town speed 35 mph. the SES light begins to flicker.
then the car shuts off, like the key was turned off.
went to restart and just turns over, reset the ecm tried again no start. push on the gas a little mabye half way and try starting fires up.
running a bit rough now, scared to drive it around again in case it leaves me stuck any ideas?

im running 55's modded ecm by turbo bob, reds chip 93, new coil pack and module wires, good fuel pressure.

why don't you try reseating the chip in the ecm?

Any trouble codes set on your scan tool?

I was gonna say the same thing as Steve.
Had the SES light twinkle at me a few times before.
Got it pulled over before the car ran like crap though.
My problem actually turned out to be a slightly corroded pin in the ECM where the chip goes.
I swapped out my comp. Hasn't done it since.

Car goes into limp home mode when this happens. CalPak is programmed for stock injectors in this eventuality so, if that is your problem, you are pumping twice the gas that it should have into the cylinders which will make for bad running and washed down cylinder walls.

Well the chip is fully seated into the ecm, i checked that twice.

It didnt go into limp mode, ran fairly well just not like before this happened.

uh there were no error codes given from the scanmaster when this happened,

the ses light flickered then the car shut off.

any chance its the crank sensor?
i chaged it awhile back but didnt gap it or anything just bolted it on

You should check it and be sure that the gap is reasonable on all three blades.

Does the car run right when the engine is cold? Thinking about the module.
