Check for a plugged cat convertor, especially if you have a noticable power loss. Also check your idle air control valve which, if faulty, can cause a start/stall condition. Your truck has OBD 1 electronics, which won't set codes for a lot of problems, unlike OBD 2 which covers a lot more areas.
A Haynes manual available at most local parts stores for under $20 is a valuable tool. The front of the book has a number of well written troubleshooting procedures and repairs. Good luck.

when it dies pull the coil wire off at coil have someone crank the engine should have loud and visible spark out of coil. if not the ignition electronic module could be bad if you have spark then you need to hook up a fuel psi gauge to the injector fuel rail port and drive while watching the psi if fuel psi drops at the time of cut out then replace pump
also could be a ignition coil braking down
