gas po ba yan o diesel adventure?

have your fuel system pressure and volume delivery checked. your symptoms seem to be a result of low voltage output from the ignition coil. under load, the spark is barely enough to ignite the air fuel mixture. the available voltage from the ignition coil must be at least 30000 volts to have a satisfactory performance.
