so my truck just recently started literally turning off while driving. very dangerous indeed. it happened a couple times last month and today it happened 4 times! one time in the middle of an intersection! power steering cuts off so i cant steer very well and the brakes go to hell and i had to use the e brake once so i wouldnt die. i had a dodge years ago that did the same thing when i was going down a bridge and nearly ended up in the river. anyone have a clue as to whats happening? engine cuts off, check engine light comes on, but the air, lights, and radio stay on. computer problem? taking it to my mechanic on monday.

 

Is the CEL on?

 

it only comes on when it dies...the engine straight up just dies without any noise or anything. then the check engine light turns on. after i put er in park she refires up.

 

Can you hear the fuel pump?

 

nopes

 

I am not 100% sure, but there are relay boxes on 5.0 cars, and I am sure our trucks have them too, it could be that or your fuel pump has gone out. How many miles are on your truck?

 

approx 98,000

 

What year and engine let me do some research.

 

1998 f-150 4.6 L thanks! i am also looking up some similar problems.

 

I would suspect this first.
