Truck died

Maybe you guys can help me out here. I was driving my truck home today when it just up and died like the switch had been cut off. Its a 1986 F-150 , 5.0 EFI. Anyways when I tried to start it again, it would just spin like it wasnt getting any fuel or spark. Ive checked and it is getting fuel. As far as spark, the 3 wire plug that goes into the coil, has fire to it, but Im not getting any fire out of the coil itself. Put in a new coil and still nothing. The coil was getting hot also, but I cant find any grounded out wires. Only other thing I could get it to do, was wiggle the plug that goes into the bottom of the dizzy and I could hear things turn on and click. Thanks ahead of time for any help I can get.

Could it be possible that the points are going out?

My guess is a TFI module. http://www1.autozone.com/servlet/UiB...3d800a50b5.jsp

The truck just got a tune up not to long ago, but I can try the TFI module.

MY 4.9 did the same thing. I was driving down the road and it just shut off. Turns out the gear on the bottom of the distributor had broke in two, so I put a new distributor in it timed it and was fixed.
