From what I've been reading it seems to be a worn pip sensor in the distributor.

Would the pip cause it to run erratically and died when it gets warm???

It can. The tfi module can as well. Here's the procedure to test them so you're not just throwing parts at it. http://351winsor.com/joel/Ignition_Systems/tfi2.html

I have replaced the TFI and it still does it. Could the IAC be a factor?

The iac shouldn't be a factor. If its not the tfi module it's likely the PIP in your distributor.

From my understanding, the IAC has more control when the car is cold.

I've changed the PIP before but unfortunately it could be bad again -_- really thinking about buying a new MSD distributor

Would the TPS be a factor because of the surging idle it has? And also when it's surging the volt gauge is erratic as well

Surging Idle could be vacuum leak (usually is) could be dirty MAF, bad ignition timing. Could be a lot of things... Really good sticky on it at the top! Lmk if you need help tracking all this down... I recently had to deal with the same thing

you can also have a short in your charging system since your volt gauge is erratic. this can domino effect into your ignition system.

True true, but if his Idle is dropping really low due to surging his alternator might not be outputting enough... just a thought, good call though

i would do the ignition systems tests previously mentioned. and to answer a earlier qustions. if you bought a cheap/china/autozone tyoe pip then yes it could go bad quickly. but as stated i would test it, not just replace it.
