I have a 98 Blazer. About 2 months ago it started acting up periodically. When I first start the motor and drive, it would do fine. Then after 20 minutes or so it would start losing power and can't get the rpm's over 2500. I would push the gas and nothing, but I noticed the RPM tack would go down when I did this. I'll pull off, shut the motor off, and after 2 minutes I would start it again and gain some horsepower back good enough for a couple of miles and then I repeat this again.
