Default 1992 S-10 PU Stalling

The car needs a prime of gas to start it, once it starts the eng will run for a few seconds by itself then stalls, feather it and it starves and dies. Did a complete tuneup NG. I replaced the MAP sensor NG. Disconnected the alt 2wire plug and it ran fine? Please help in any way possible. TU

Thanks Mike
I was going to try and get a fuel pres reading over the weekend, the only thing throwing me off is the alternator thing where it stays running when unplugged?

If you unplugged your alternator the engine will just begin using your battery, Sounds like you have a bad alternator browning out your electrical system. Have it tested for free at a local parts store.
