Default 1994 Corvette with LT1

My friend has a 1994 Corvette Automatic that will every so often bog down and stall no check engine light he replaced alternator, optispark, and battery I was thinking it could be the ignition switch or fuel pump but wanted to see if anyone else is having the same problem

That's some expensive guessing your friend has done. Recommend they get a FSM and perform appropriate diagnostics.

Could be fuel pump. Could be ICM heat soak, 'tis the season. Could be other things.

Need more detail than this. When does it happen and under what conditions? Can he restart the car when it stalls? After how long? Does it sometimes bog down but not stall?

Yeah he doesn’t like to listen to me most of the time but it usually will always stall and it will stall in pretty much any condition but from what I’ve experienced is more prone to stalling in colder weather like rain and during night time the car restarts no problem after a few seconds of waiting but sometimes it doesn’t start back up and you have to wait a few minutes
