Default Car runs like crap when it's warm..

This just started happening..

My car runs fine when I first start it up and water temp is down, but when water temp is at normal, and I shut it off, and turn it back on (Like going into a gas station or whatever), it'll idle like crap for about 2-3 minutes, and even die if I don't keep giving it gas..

Any ideas?

If that's the case then it'd be too rich........have you run a koeo/koer test to check for any codes?? also I'd check fuel pressure and see if you have leak down occuring like due to a bad check valve in the pump or also have you pulled the vaccum line to the regulator and checked to see if it's wet with fuel inside due to a possible ruptured diaphram...also if the regulator is bad it could cause pressure to intermitantly spike..I had a e.350 van domthat one time..out of the blue it run bad briefly then good..anyway just a few ideas to check

Possibly TFI?

I've heard many stories of heat causing the TFI to not work properly. Search around see what you can find, you may have to relocate it.
