I doubt from your symptoms that is has anything to do with the fuse box like the problem I had.

That is definitely not good. You need to remove the SC and lower intake manifold and replace the gaskets asap.
A good scanner should be able to pull all the stored codes to help diagnose the stalling problem.

I see Silverbullet already responded.

I also don't think this has anything to do with your problem but could be good info to know. It'* a long thread - the problem was solved on page#7.

Did you ever check the coils?
I'd like to see you check the spark plugs after it stalls to see if there'* any sign of coolant on them.

it all started when i changed my supercharger tensioner pulley, if there was something wrong with the crankshaft would that cause my car to stall and sputter like that.

the problem was my ignition switch....

Glad to hear you figured it out. Any details?

not really it was just the ignition switch but my car is running alot smoother since i did my LIM

i just had the same problem as you i had it out the dealership and it took them 2 weeks to figure out it was that causing the startup trouble because it wasn't doing it on every start up but after the fix i haven't had a bad start up yet
