any ideas why id lose spark and fuel at the same time? 3.0 v6

driving down the road fine when it just died,...no idea why

this sucks....please help me haha

EFI fuse?

ignitor,pick up in the dist,bad connection,
Bigblock

this happened to me. my o2 sensor wire rubber raw aginst a heat shield and was causing it to short out when i was driving, killing the truck. i went through about 20 fuses before i figured it out.

where is the efi fuse located? i already put a new coil/ignitor so i dont think its related to that,

maf sensor could be it, my cars camshaft position sensor went bad on me and thats what my car did. Id be driving even on the high way and it would like either just die or it would like back fire and then die and id have to get off the road and try and get it started sometimes it took me 25 mins to get it started again.
