Wait an hour then cranks but will do it again
Check for spark at plugs when it will not run. Spray some carb cleaner into the throttle body and see if it runs for a few seconds on that. Post results.
Cranks, but won't start? Catalytic converter. exhaust can't escape. No air out, no air in. Next time, put your hand over the carb/ throttle. Little or no suction. Dump the cat. Being an 89, could be other things. Old engine.
Does it have a distributer ? or DIS ignition system ? Sounds like bad ignition module .
Testimonial: "new module new coil new pickup coil new pump relay new fuel filter"
do a fuel pressure test .
12 psi
What's missing when it won't start , Spark , fuel .Something has to be missing .
fuel
How does it run those 10 min.?? IF the Cat was that bad it wouldn't start an run at all

Check fuel pressure , go to you tube an check videos on fuel pressure testing
i did a fuel pressure test it was 12 psi
it runs great for the 10 min.it will run for an hour in the driveway but not on the road
Did you have a scan tool hooked up to check engine sensor data ? specifically the coolant temp. sensor
cts was one of the first things i changed after rebuild 4 mo. ago
Does the check engine light work , I mean when you turn the key on ( not to start just on ) explain won't crank ,when it dies does the engine turn over but doesn't start ? Are the injectors squirting fuel after it dies . You do have Two TBI injectors . Computer, engine computer ! Injector drivers inside computer !
Bad ECM !
