the motor starts fine,untill a few minutes after it starts
it will only idle but will not rev up at all. I put it in gear
and it will slowly go up to about 20 to 25 mph.
after that it eventually dies. please help!!!!!!!

check your engine vacuum, if it's low it may be a plugged converter. If it is it should be warrantied until 80,000 miles. Make sure your fuel pump has good pressure as well. it shouldb e 40 p.s.i. minimum. so it could be a clogged fuel filter causing low pressure.
