Sound like you might have a air/fuel metering problem. Your engine may be running lean possibily because of a dirty or malfunctioning MAF(mass air flow sensor). There are may ways to diagnose a faulty MAF sensor but they all require diagnosistic tools & a good understanding of the fuel delivery system. What clued me in on this problem is when you keep your gas pedal down (WOT -wide open throttle), the fuel system is tricked into a open loop & runs richer then the values it learned in closed loop which in turn keep the motor alive.
Hmmm. Sorry I got a bit technical!
When your MAF sensor is bad or dirty, it under estimates the amount of air going to the engine which mess up the amount of fuel being sent to the motor. So bottom line, it's starving for fuel!
You might want to try this, disconnect the connector to the MAF ( located after your air filter housing). If the problem gets better, replace the MAF. If not, bring it to a local repair facility. Have them check it out.
Hope this helps. Good luck!
