possible your fuel pump is going, need to have it pressure tested, i would also look at the throttle body, it may need to be cleaned.

The fuel pump was on my mind I took the Jon Jones dealership yesterday they hooked it up and done a diagnostic test on it they thought I had the wrong key for the car so they sold me a key that has a chip in it it didn't work so now they're going to give me a free diagnostic test in the morning but I think it's the fuel pump because it starts up three four seconds runs idles great then just dies
