Change the fuel filter first, it could just be a bad filter. Most of the time if the Fuel Pump go's bad the Engine will not run since there is not enough fuel pressure for the injectors to run.
A dirt fuel filter will still have fuel pressure but not the proper fuel rate. When you buy the Fuel filter at the parts store, like Auto Zone or Parts Source (they scan for free) if the truck can make it there, have it scanned for any DTC codes to see if there are any other problems that may be causing the problem like a bad Fuel pressure regulator or another sensors that may have gone bad making the truck do what it's doing.
The other thing to, Look for any corrosion at the Fuel Pump harness from the frame to the tank. See if there is any damage to the wire's and connection clips. But if your going to have to change the Fuel Pump, change the harness too. The extra $12.00 for the harness is cheaper then dropping the gas tank again just to change at 12 inch wire harness.
Good luck and hope this help. PS don't trash the old Fuel sending unit. You can always drill out the old Pump from the unit and replace it with a more reliable pump.
Yes, it does sound like your fuel pump may be going bad.
The first thing I would try is to change the fuel filter. If the fuel filter is plugged, it will cause a low fuel pressure and the engine will not run good.
After you change the fuel filter you will want to do a "fuel pressure" test. You can borrow a fuel pressure gauge or but one ( $40 US ) connect it to the fuel rail test port on the engine and start the truck. Your fuel pressure should be 45 to 55 lbs.
If you have more questions, let me know.

is it an ignition [loss of spark] =fuel issue [fuel pump--filter] scan vehicle for codes active or pending ---usually fuel pump--cat converter--short in wiring dont pull a code --
pretty sure its all in the tank module, here's a rebuild kit for $25, pump,o-rings,filter to copy and paste https://www.1aauto.com/1994--dodge-spirit-electric-fuel-pump/i/1afpu00413?f=767842&y=1994&utm_source=bing&utm_medium=cpc&utm_campaign=Shopping%20Campaign%20F-L%20-%20Medium&utm_term=4576854590039245&utm_content=Shopping-FPU
have someone beat on the fuel tank with a dead blow hammer or rubber mallet while you crank the engine over. the fuel pump is located inside the fuel tank and this should get it pumping again, unless it's totally dead. this should get you back on the road but it's only a temporary fix.
Sounds like the fuel pump went bad, a test you can try , this is not a sure test just a quick check, have some one beat bottom of the gas tank while you try to start it, this sometimes shakes the pump and make it run again, if it does start the pump is still bad.
No, no reset for an S10. There would be a fuel pump relay under the hood in the fuse/relay block. And also a 10 or 15 amp fuse for the pump at this junction block as well.
Check the fuse, then find the tank electrical connector, pull it apart and find the gray wire -the fuel pump wire. Clip a test light lead to ground then put the tester probe into the gray wire terminal on the harness side of connector. Now have a helper turn the key to start and crank the engine over. The test light should light up if your electrical circuit is working. Before you drop the tank to investigate the fuel pump (it probably needs replacing), check if the ground for the pump is alright. Maybe when you hit the curb, you jarred loose the ground connection.
There is no switch of that kind, the most common problem would be a bad fuelpump, a quick test is to have someone crank the engine while youi beat on the bottm of the fuel tank, this sometimes shake the pump and gets it going, truck may start if it does then you will know its a bad fuelpump and needs replacing, the pump is located inside the fuel tank. if truck doesnt start then the best thing is to test for power at fuel pump connector and if theres power to it then replace it.
beat on the bottom of the gas tank with a 2 x 4, while someone tries to start the car........if it starts, replace fuel pump and filter!
it's the good old W.V. TEST!!! yet it works.
it sounds like the fuel pump needs to be replaced
the fuel pump is an electric motor the fuel in your tank keeps it cool but when you run the fuel dry the pump overheats and can seize
