4.0 shuts off

I have a 1994 jeep grand cherokee 4.0 and I have been having problems with it shutting off. I changed the fuel filter, dropped the gas tank and drained the gas and cleaned it. It started, i drove it to get gas and it shut off again when I got back. It has done this several times now. It always cranks the next day. I don't know if its running too rich and flooding out or what the deal is. Any advice would be appreciated.

When it dies can you start it right back up? If so, sounds like the Idle Air Control Valve. Not 100% sure but that's what it sounds like.
