So I was on my way to my parents house when my ride started losing power, then it all of a sudden shut off. Been losing power a couple days before that. We thought we picked up water, but no water in the line. So now it will crank up fine and will idle an rev up sometime but eventually lose power again. Could you please help? Maybe clogged filter or something else? Thanks

Clogged filter, fuel pump failing and providing low fuel flow. Describe how it loses power, under load? Just setting at idle? Anything else odd?

Sorry took so long. But we replaced the fuel filter the other day still doing the same. It. Will. Crank up. An sometimes idle. An it will also stay running for a little bit but then stall. We cant hear the fuel pump kick on. But we think its a manual fuel pump.

Sorry we just need more information to help you. When the engine stalls can you check it see if the ignition has spark? This way we can start to narrow down the system that is having a problem.

Here is a guide that will show you how look toward the easy test at the bottom of the guide.

Please let us know what happens and upload pictures or videos of the problem.

Cheers, Ken
