Run a fuel pressure and flow test, if it fails replace the fuel pump, fuel filter and fuel pump relay. If no problem with the fuel pressure then the Spyder injection is the next most common failure, I had a problem with my old Tahoe with one injector leaning out during full operational temps, I was able to correct the problem by filling up with Chevron fuel for about 3 tanks and then went back to my regular fuel supplier and putting in a bottle of Techron in every tank full, ran it that way until I sold it, otherwise I would have had to replace the entire Spyder system, and that's not cheap. You may want to consider getting a live data scan performed also, you may have a sensor misread fooling the computer, ACT, ECT, TPS can cause your symptoms too. HTH
