What remote starter are you using? Please connect the Dark Blue wire (GWR) on the 6 pin connector of the evo-key directly to ground, red led should light up, after a few seconds, at this point remote start the vehicle. if it starts, let it run a few minutes, then shut off. disconnect GWR from ground for a few seconds. reconnect back to ground, red led lights up, remote start a few seconds afterwards,
If your vehicle starts reliably by performing above test, then there is an issue with your remote starter's GWR timing, it might be coming on too late and too close to when the vehicle's ignition lights up.
You can try connecting the disarm wire of your remote starte with the GWR of you remote starter to the GWR wire of the evo-key, in doing this you are turning on the evo-key sooner.
