ive got a 1990 gt with a tremmec trans. when it is cool it has full power and no problems but after running for over 20 minutes it looses power after 3000rpm. what can this be? ive heard that it might be the fuel pump while others said its not. it seems like the problem is directly related to the engine temperature once it reaches a certain temperature the problem occurs. i will be thankfull for any ideas
