HAVE YOUR EXHAUST CONVERTER CHECKED! IF IT'S BAD AND YOU HAVE IT REPLACED, DON'T LET THE ONE THAT REPLACE'S IT TAKE YOUR OLD ONE!!!!! IT'S WORTH ABOUT $250.00

SOURCE: hesitation, stalling like out of gas

Clogged Catalytic Converter. What happens is as you push down harder on the accelerator you force more gas into the system causing a slightly richer mixture and more exhaust flow is neccessary. The easiest way to look for a clogged cat is when it's dark out take it for a ride causing it perform it's problem look under the vehicle if the cat is literally glowing red hot you either have a clogged cat or an extremely rich fuel mixture.

SOURCE: engine misses 4.9l

here is the next step, you buy a fuel pressure test gauge from a parts store and hook it up at the test port at rear of the engine on top, it looks like a tire valve but metal, will have a plastic cap on it ( or should), test the fuel pressure should be around 50 PSI at idle. How is the fuel filter, ever been changed? it is due every 30,000 miles

1989 is fuel injected, on the intake there is idle air control valve, make sure this is not dirty, also you may want to check the coolant temperature sensor, if the engine thinks it is warmer then waht it is the fuel air ratio will be off and your truck will run bad.

It sounds to me like you replaced everything but the most likely cause of a stall while driving...The crank sensor.
