89 dakota cutting off

89 dodge dakota 3.9l auto trans truck will run fine then cut off and will not start. let set for a while then it will start.after it cuts off and wont start i get no power to the coil.have changed coil pick up in dist. and brain box still same problem.

If there is a ASD? If so try replacing it.

what is an ASD and where is it located

Figure four after opening the link shows the ASD relay http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c1528007154c I am guessing it may be in a fuse box under the hood

ASD is Auto Shut down relay

I will try it thanks.

tryed the ASD still cutting off the coil is getting very hot any ideas thanks
