Car won't stay on!
 

Hey guys, hopefully I'm in the right section for this question.

2000 Trans Am 6 speed
LS6 motor

changed the fuel pumps, new filters, fuel pressure is ok, no vacuum or fluid leaks. Car won't stay on, any ideas?? It starts up fine but after a few seconds it bogs out and dies, 5-10 seconds usually

Previous symptoms: would idle funny, would almost stall out coming to a stop, random jerking while cruising on the highway (that's why I changed the pumps)

Any help would be appreciated
thanks!

Have you checked the mass airflow sensor?
