89 S15 Jimmy shut off while driving

4WD
Manual transmission

I've been having starting issues in cold weather for a long time. Ran fine once it was warmed up. This year things took a turn when it started stalling. At first it was like it wasn't getting gas, or stopped getting gas. Then it would kick in. Found a vacuum leak and it seemed better for a few days. Then it just stopped while I was driving. Not putt-putt or studder, just quit. Got a MAP error but it checked out okay. Thought it was a clogged vacuum port on the throttle body so, ended up rerouting a vacuum line and it ran great. Really great. Until last Friday when it quit again. I'm at a loss so any help would be appreciated.
Parts thrown at it so far:
Plugs and wires
Idle air control
Coolant sensor
O2 sensor
MAP sensor and connector
Vacuum lines
Also, it's getting gas but now refuses to start at all.

Plugs cap rotor , new distributor, map sensor, coil , new fuel pump, just loose power every now and then, rest of the time it runs good. , just going to keep on working on it and maybe some time it'll fix it, soon going to be a new truck, just keep replacing parts. Nobody has a definite answer to this.
