I have a 1999 Tahoe with about 164000 miles . no problems up till now . I can start my tahoe fine it runs fine , but after about 20 to 25 min. running it does not respond. That is i push the accelerator and the more it chokes , bogs,no response. I can turn off for 10 to 15 min. and it will start right up again,but after a few more min. same thing . I have been told to check EGR valve,fuseable link,map sensor and even some vacumm lines . Please shed some light ?
