Lately my 91 w150 318 auto has been cutting out while driving. It only cuts out for maybe a second tops but it only seems to do it when I hit bumps (potholes speed bumps ect.) Or when stomping the throttle. Mostly from bumping the truck around. My guess is fuel or electrical but I'm not sure where to start. Any ideas? Thanks

 

check the battery cables/ make sure every thiing is making a good contact and is tight and clean. also suspect could be the firewall bulkhead connection. prolly not anytjing to do with fuel.

 

Ill check the battery and try to find the bulkhead connection lol
