Engine fires then dies, runs terrible

Looking for any help or ideas...
I have a 91 Jetta with a 98 VR6 swap. Car has been running great for the longest time until the last couple weeks the idle has felt like its been getting a little rough. Then this morning I cranked it over.. it fired then died.. did it three times till I gave it throttle and it struggled to stay running... then it idled at about 500 rpms... so I shut it off and left it and as I was walking away it smelled super rich out the back...
Its OBD2 but I don't have a port to check codes...
Any ideas?

Update: I unplugged the battery for a half hour then hooked it all back up and the car fired and ran good again... Any ideas what could have caused the problem?

Unplugging the battery would cause the throttle body to realign itself when you plugged it back in. Maybe check your TPS and throttle body, also check your MAF.
