Hi I'm new to the diesel world and recently bought my first diesel so I haven't learned too much about them yet. I've been having an issue to where the truck will start to bog down and lose power at like 1.5-2k and it'll just drop from there and occasionally die. The issue is random I drove to 45 mins last night with no issue, then this morning it died about a block away from work and wouldn't start back up. I'm thinking fuel pump, fuel filter, HPOP or CPS
