And reading your other threads here,i'm allmost certain your ICM is acting up.Coil packs dont go bad like that without something overloading them.The ICM's were common to bite it on older Fox body 5.0's.Being this is a V6 on a new style only in it's 2nd year,they were still using the old ICM's.Ford rid the stang of the ICM in '96 and later.The PCM controls all that in those later years.

Ok,I believe I have your problem narrowed down.The misfire and erratic throttle response...stalling....then blown fuse,which is all coming from the second coil within the coil pack itself.To be more specific,the coil that fires Cylinder #6 and Cyl. #2.
The reason why this coil is acting up is due to the fact,the primary for Coil B is shorting to Ground or has a bad or possibly corroded connection.This connection problem or short could be in a number of places.First you'll want to check the electrical plug that goes into the coil pack.This connector is located on the back of the coil pack and has 4 wires coming off of it (3 yellows - 1 red).The 3 yellow wires are in order on the right side and the red is on the far left end of the plug.The culprit wire you are looking for will be the center yellow wire (Second from far right side).The terminal for this wire inside the plug could be loose or very corroded.Follow this wire all the way to the ICM.The wire insulation could've split from something rubbing or cutting into it.A bare spot exposed anyplace it's not burried in a harness could be touching or vibrating against the body or any ground.You'll have to look very carefully.Also check the connection on the ICM side.But this time check both the harness terminals and pins/contacts on ICM itself.No need to check the coil pack itself since basically it's known the coil pack itself is not the main source.
Take your time on this one.If you can,have someone start the car and keep it running.During this time,follow the wire and all possible harnesses and wiggle it every inch untill you get to the ICM.You'll know if you hit an "Invisible spot".Careful around drivebelt and pullies.I once had my hand get pulled up between the Alt. pully and the belt.I was doing something to the pully itself while the motor was running and not being careful,the pully just slung my hand to the left and right into the belt track.The pully just sucked it right through an entire revolution and popped the belt off in the process.Believe me,It wasn't nice! So,you get the idea...back to wiggle test....Tell the person sitting in the car to keep throttle at a set spot.Just enough so it doesn't stall out.If you hit a bad spot,you'll know as your RPM's may smooth out or eratically change.
This wire or the terminals on either end is definately your problem.Also it is what is setting the P1353 code.Let me know if you need more info.
