Its flood a tranny sensor causing a circuit fault, rain water conducts electricity. Locate this/these sensors and coat them with a sealing agent, your local auto parts store will have the stuff you need. No water, no short.

SOURCE: truck stumbles just off idle
may need to have a fuel injection service,but when i worked at chevrolet i believe those year trucks were having a problem with the throttle body sticking

Have you changed the fuel pump yet?I had the same exact problem.I replaced my fuel pump with an AUTOZONE PIECE OF JUNK fuel pump.That pump lasted almost 2 days.The second day i had it the truck didnt want to start but it did and it ran like ****,and when i put it in gear it ran as long as I didnt touch that gas pedal.You could go get a fuel pressure test or just replace it,your call.You might want to check your filter too but im sure its the pump.Good luck

Check the vacuum line to the fuel pressure regulator and check to see if the fuel pressure regulator has gone bad. Give the throttle body a good cleaning and the injectors too. Do not use carb cleaner, it's to corrosive for the gaskets used in the throttle body. The other thing too that would cause this is a stuck or bad EGR valve, Try cleaning the EGR valve too since your cleaning the throttle body. Good luck and keep me posted.

is commonly caused by a dirty automatic idle speed control valve and
throttle valve but always run a OBD2 (1996 and newer) or a OBD1 (1995
and older) fault code as well as the cleaning procedure. Buy a can of
throttle valve cleaner (do not use carburetor spray cleaner!) from
NAPA or Carquest (made by CRC chemicals) and spray it into the air
intake while the engine is running, use up about 1/2 the can, engine
will try to stall hold the speed up, shut it down and let it soak for
30 minutes, restart and blow out the remaining fluid, shut it down
and disconnect the negative battery cable for 5 Min's to reset the
base idle control
