I had similiar problems with my car it would not restart hot and car even shut off once at 50mph like i turned key, usually after atleast 4 hours it would start right up. Over the years with these symptoms it turned out being PIP module in dizzy twice and once with similiar symptoms it turned out being the TFI. When it was PIP my tach was jumping around, anyway i ended up buying the same TFI module at Napa ive been trouble free for a couple years now. Just happen to have a pic handy lol
Hmm... so what fixed your tach problem, The TFI or the dizzy?
I replaced both and still no luck. The dizzy is a motorcraft but the TFI is a cheapo. I did have it tested and it tested good.
Maybe it's a quality issue? Perhaps one from NAPA? I hate to keep throwing money at this though. I've already dropped $200 on this stupid tach problem..

my tach stopped jumping around after i replaced the pip sensor in dizzy i have Autometer gauges. If you have no other problem more than your tach is jumping around i think the problem is with the tach
