My car did this a few months ago, it started bogging down once warm. literally falling on it's face only to perk up again. Today, it did it again and I could floor it and all it would do is surge to about 1500rpms, then flat line to barely running. like 300 rpm only to surge again. Every now and again, it will rev to like 4 grand, then continue stalling. Its like it is starving for fuel, but when it does it, it reeks of gas but will never backfire? Sometimes it will even die. I am a decent mechanic but damn I am stumped. Also, if I pull over and stop, for like 20 minutes, it will drive for another 20-30 mins. I'm friggen lost.

Sounds like the filter sock in the fuel tank is plugging up as the car drives.

Some of the crud falls off w/no suction while stopped.

 

Test drive it w/a fuel pressure gauge attached to be sure.

it quit already... sneaky bastard like torturing me for all that wheeling on bad ball joints

 

really though, its super rich when this happens, like I could set fire to the exhaust gasses. I don't think its fuel...

I think its bad gas, both times it has happened, it has been after a heavy rump roast rain and I have bought gas from the same QT which happens to be at the bottom of a hill. I got it to run that day, and flogged it home and now it runs just fine. I think I was trying to burn water lol. Next time it does it, Im going to add some ISOHEET water eliminator.

 

I came to this conclusion last night...
