Engine dies
So when I drive my truck I’ll be crusing in 4th gear and my engine will die. Then I can put it in neutral and start back up like no problem. I have replaced the fuel pump, fuel cap and sending unit. I don’t loose headlights or anything the engine just dies and restarts like nothing happened any clue what this may be?

Re: Engine dies
Tell us more. For example- how long does it run before this happens and/or what type ignition and coil ? Cruising in 4th. Is that at 55 or 70 ?
New fuel filter ? Engine and carb ?

Re: Engine dies
It’s a 72 350 with 50,000 miles on rebuild with a quadrajet and can be driving anywhere from 50-70 on flat interstate and the few times it has happened it happens after about 10 mins of running. Also have a hei with a new module installed new plugs and wires. Yes new filter.

Re: Engine dies
Make sure your HEI has a full 12 volts to it, they cut out like you describe when they are getting less than 12 volts.
Quick test is to run a 12 ga wire straight from your battery positive to the HEI bypassing the ignition switch and take it for a drive to see if problem persist. I have found over the years by trial and error when it comes to HEI's I always run directly from ignition switch to HEI bypassing the fuse panel which can also be a problem, not always but can be. I would suspect the coil last as HEI coils seem to be pretty bullet proof |

Re: Engine dies
Hey Noah did you ever figure your issue out? My 58 Apache, 350 is doing the same exact thing.

Re: Engine dies
Did you use the designated heat sink grease on the back of the new module? Also, my second 72 went through 3 Quadrajet filters in less than 100 miles until I installed a canister filter between the pump and the carb. The truck came from a sandy soil region in west Nebraska and had been sitting for years, the tank was full of fine grit.
