Default UPDATE: STUTTERING PROBLEM

Ok, today my problem kept occuring (it was about 85* F). i am thinking it is the TFI coil. The outside temp. cooled off significantly, and started raining. within 5 minutes my car started to run normal again. temp. dropped, engine bay cooled off, coil cooled off?... GRABBEM what do you think?

it will run fine for about 20-60 minutes, depending on the temp. then it pretty much stutters really bad out of a stop in first gear, then some of second. once i get going, it gets a little better but still lacks a significant amount of power and torque.

i forgot to add, that eventually led to stalling, and not being able to start for a few minutes.
