1991 Chevy S-10 4 cyl Two Wheel Drive Automatic

This truck has trouble staying started. As soon as you let off of the gas, most of the time, it stahls and is very hard to get started again. It seems like it isnt getting the gas it needs to run. When we do get it started we have to keep reving it up to get it going! Sometimes we have to drive it with two feet to keep it running!
Just wondering if it could be the fuel pump or filter or something else!
Thanks

Start with the basics, and work your way up, Last tune up was? Wires plugs ALL filters? If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!
