That could be any of a large number of reasons. I would start by insuring spark plugs are in good shape, same for plug wires. Then I would suspect the fuel system. Dirty gasoline, water in the gas, etc... Measure your fuel rail pressure (assuming fuel injected). A failing fuel pump on an injected engine will result in a rough idle, lack of power/acceleration, and very poor overall performance Much the same could take place with a dirty fuel filter as well.
A failing pump will commonly "slow down" due to internal friction, and lower the rail pressure enough to cause a vapor lock condition in the fuel rail. This symptom if vehicle actually does run, usually gets worse as the vehicle warms up. I quick check would be when the symptom is present, shut the engine down, and immediately and carefully depress the shrader valve on the fuel rail VERY BREIFLY. if air (fuel vapor) comes out, this is likely your problem. But again only very briefly, gasoline landing on a hot engine could very easily start a fire! Thus a very quick pop of the valve is all you should need. There should be no air in it.

Why would your car idle fine but sputter when you accelerate?
There are a number of reasons why a car would idle find but sputter when you accelerate. It could need a new spark plugs. You may also have to replace the filters. It might also be an issue with the air flow.
What would cause a 1999 Saturn sl2 to sputter when you accelerate slowly when you punch it it will rev up then kick in and wont sputter but will when you accelerate normally?
MINE WAS DOING THE SAME THING AND IT WAS THE EGR VALVE!! THAT FIXED IT AND IT'S RUNNING GREAT!!:)GOOD LUCK
Why would 95 silverado not accelerate and idle rough?
There could be several reasons that your 1995 Chevrolet pickup truck, will not accelerate and idles rough. The most common reason is a plugged fuel line.
Why would a 92 Paseo take a while to accelerate and sputter and want to shut off when you try to accelerate from a complete stop?
sounds like a lack of fuel. 1st I would replace the fuel filter. If this does not help, have the fuel pump checked.
Why would a 2003 Impala accelerate slowly It sometimes will sputter - I have replaced the fuel filter and air filter. 3.8L?
not 100% sure, but check your fuel pump
Why would a 2000 Ford Taurus Sputter and Miss at running speed and not when idling and not when you accelerate?
It may be a EGR valve issue. This valve is normally closed at idle and opens at about 40mph.
What would cause a 2001 Toyota Corolla to stall out when you first accelerate and after choke and sputter for a few minutes?
it may be the maf sensor i got a corolla 2001 too do you have any codes ?this is a old question thought.
Why would a 1992 Jeep Wrangler YJ 4-cylinder sputter die and not restart for 20 min at 3200 RPM?
Have you checked the catylitic converter? Had a Datsun B210 that had the same symptoms. Took the converter out and the honeycomb would clog after 20 - 30 minutes driving. Just a thought!
What is wrong if a car starts but stops when you accelerate?
A problem with the fuel system. I'm assuming the fuel pump or carburetor/fuel injectors. I had a 1987 Pontiac Firebird that would sputter for a few seconds when you pressed on the gas pedal. Never got it checked though but I assume that would be the problem.
Would bad heater core cause car to sputter?
No
