uhhhh........maybe limp mode? what kinda ecu u running? does the engine light come on at all? do u have a wideband to monitor a/f when this happens? maybe replace ur map sensor. i dunno man this is a doozy, but id say see if its throwin codes and pull them if it is. sounds like either an ignition issue or a tune issue.

 

it needs tuned and it has an engine light for the map sensor.

 

A bad map will make the car run horrible. Change it immediately!
