car shuts off and bogged tach jumpy when driving for a while
got car tuned at shop, on my way back a good 30 miles from shop the car bogged and started shaking a bit, tach would spike down to 0 and back up to idle, and i just kept driving and it kept doing that for a bit then all of sudden power shut off, battery light oil light all came on, funny thing is i can still rev engine but wouldnt be going any where. i stopped the car, let it cool for a bit, then was able to drive again, and another 20 minutes or so it happened again, so i had to let it cool again. I have no CEL on either. so i was about 80 miles from home, stoped at rest stop, unhooked battery for a few seconds then pluged it back up, and then started up and took off on the highway again, but this time, i turned the heat up all the way and blasted it on and for some reason i was able to drive all the way home with no problems. do you guys think its an over heating problem somewhere? someone told me fuel pump maybe going bad and over heating, another said main relay going bad and over heating, and another said since i only had a halfsize radiator one row non aluminum for a big allmotor build it may not be cooling car enough, any inputs really need help!

Re: car shuts off and bogged tach jumpy when driving for a while
sorry another thing i forgot to mention, before that happened, i drove around for a while and then let the car sit in my driveway and left the car on, and after 15-20 minutes of idling it all of a sudden shut off, went to start it up and started up fine. so gotta be something over heating and going bad?
Re: car shuts off and bogged tach jumpy when driving for a while
sounds like you could have several different problems, but is it actually over heating? That is the real question. From everything you said it sounds to me like it's actually an ecu problem, could be the map the tuner made, or just a bad ecu. I would try the ecu first, I have seen crazy things like this happen and the ecu was to blame....

Car was tuned no cel and I have a switch for my fan but I'm not sure if it's actually overheating, my temp gauge doesn't seem like its overheating. I also thought maybe it was a bad tuned chip.
