Welcome and congrats on your purchase....don't like to diagnose based on symptoms but I'd inspect the air filter and if good I'd try cleaning the MAF sensor...REALLY need a scan tool to look at data...could also be a "fuel delivery" issue too...fuel pump or fuel filter.

Fuel filter? Plugs? Wires/coils? I'm not one for throwing money at problems, but I DO like to get all the easy/maintenance/tune up type things out of the way. I'm new to Corvettes and the LS platform, so I don't know expected service life, but on older cars if those things haven't been changed in awhile.....I like to start there. -espeically if you do NOT have a check engine light or scanning ability.

Not all codes will give you a check engine light. When looking for codes are you holding the options button and pressing the fuel button 4 times or did you have someone with a scanner pull the crank position sensor code after the check engine light came on?

When you replaced the crank position sensor replaced you then must have the Crankshaft Variation Relearn Procedure performed. If not it will cause numerous problems from starting to surging to stalling.

You’re right !!...his CKP was replaced !!...either a Tech 2 or a bi-directional scan tool needed to do this procedure !!
