Has a Check Engine Light come on? I presume what you describe is an ignition misfire under load, or loss of fuel pressure or volume. Attaching a scantool to the 16 pin diagnostic socket will show codes and pending codes. A good scan tool also provides live data on sensors air flow into the engine and fuel trim figures that could lead toward diagnosing vacuum leaks fuel system or ignition problems.
