Driving under normal conditions and the truck just stalled out. I pull over and it starts right up. NO PROBLEM Right??? Just start driving again, and I realize its going to stall after hitting a bump. Sometimes it stalls all together, sometimes it stumbles and then regains itself. Do I go buy $5.00 worth of gas and get a match??? This is killing me.

its prob something with your distributor.... check all connections with your wires to your distributer make sure the connections are clean and dry.... also check the wires going to your coil.... clean you battery terminals too it cant hurt.... you may also have a broken vacuum line it happened to me once and it was messing up my idle like crazy and i kept stalling too

You've got a short. No easy way to find it. You'll need to poke around under the hood while the trucks running and find what makes it shut down.

plus these days $5.00 won't buy enough gas to burn a truck.

Year, engine, etc. might help suggest specific diagnostic steps. Unless it's old fashioned carb without any computer control, you might try pulling codes from the PCM to see if the computer has any information.

Its a 97 Thoe Sport 2DR 4x4 with a 5.7 125.000 Mi . I just changed the distributor cap two weeks ago.. Im gonna go over the wires to make sure everything is tight.The engine light is not comming on. At a standstill the engine runs awesome, and when its driving (the last two weeks since the cap change) the power is great. I really cant go for a new truck right now and I am NOT gonna sell any of my toys. I know I cna get decent money for it, the body is in awesome condition.. Gotta figure this out. Thanks in advance

Go over the area around the cap, if it started doing this after the cap change you might have knocked a wire or connector loose.

Any chance of a problem with the fuel pressure regulator being the my issue??? I took a look and saw where the lines go in on top of the intake is a little wet with fuel. Its not pouring out but it is a bit wet with fresh fuel. Gonna change it regardless of it being my current problem. Questions, Comments, Moral Support anyone??

I realize that I'm comparing apples to oranges but,....

For work I drive a Dodge van while driving on the freeway I bumped the key with my knee and the engine died.

I restartewd it and found that just jiggling the key was enough to shut the engine off.

It seems there is a loose connection that causes it.

I know that there are a lot of suggestions but I recommend trying the cheapest ones first.

Yes, I've seen the ignition switch cause trouble. The lock cylinder usually isn't the source of trouble on Chevys. The switch is lower on the column. A defective ignition switch is usually accompanied by hard starting, but its worth diving under the dash to check the switch and connections.

btw. I would focus on the distributor since it was the most recent work. Loose connection, cracked rotor or faulty plug wires. Look for obvious burn marks on the plug wires or pop the hood at night and rev the engine to see any arcing.

I let the truck sit for a while, my work schedule has been crazy. I took it for a drive yesterday after messing with all the wires under the hood. Everything was tight and I could not get it to stall . I took it for a ride and it was still doing stalling. So I climbed on the rear bumber, jumped up and down depressing the suspension as deep as I could. IT DIED !!! Now I cant get it started at all. The pump is not kicking on at all. I let it sit, put the key in and turned it. NOTHING !! The pump will not kick on to pressurize the line. I gotta check the ground for the pump. WHERE IS IT ON THE 2 DOOR 97 TAHOE ???

Late, but for whoever else follows this thread

Fuel pump short. Had the same problems. I figured it was fuel pump from the get go, as I have a 96 Tahoe and the pump has been replaced twice under warranty. Long story short, check the plug connection to the fuel pump lifter. The wires inside the connector corrode or heat and short. Can NOT see the damage from visual, make sure you tug the wires to check. My replacement fuel pump lifter came with a new plug and service note about changing to solve this problem.
