Question about 1996 Chevrolet Blazer
A 96 blazer....no idea how much gunk is in the tank but not good operating without a filter that old of a vehicle. Junk in the injectors or as i've seen once a old fuel filter is replaced or removed with lots of miles on it the fuel pump starts to fail or just plain fails totally. The free flow is more than it can handle.

How long since a tune-up? Any applicable trouble codes? If you have the spider fuel system, that system is known for problems. I'd probably use a gage and check proper fuel pressure. Could be other issues? Intermittent can be a pain to track down.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

SOURCE: wont keep idle, car stalls out
I had this same problem on my 2005 monte carlo, took mechanic a while to figure out it was the idle air control valve. They also replace the idle air control motor.

Check the Alternator, Mine was doing something similar to it, was almost dieing constantly, at stops in drive, lights would flicker alot on bumps and up hills when rpm's would increase. Also yea mine also got worse after it warmed up, I replaced the alt. with a reman. but unless it was professionally rebuilt by a local electrical shop (which are kind of rare now a days) I would just get a new one from a local parts house, Also you pay for what you get. Do not have the shop get the part for you because they have anywhere from a 10%-25% mark up on local parts houses which is close or above what you would pay
