It has been awhile since I owned a Chevy truck, but I seem to remember it was something to do with the vacuum hose or filter getting clogged with dirt. If you wait a few minutes, it should start back up. But, it is a faulty vacuum (filter), and needs to be replaced.
There are several things that can cause your 1998 Chevy to randomly die out. The most common cause is a malfunctioning fuel pump.
Low fuel pressure.
The Sputtering tends to be a old or clogged fuel filter the engine is getting starved of fuel replace that and it should fix the problem
You may have a bad wheel speed sensor on one of the front wheels.
replace spark plugs and wires
The headlight switch could be the problem
allot of reasons check the carb. check for vacuum leaks. check the timing. check the comp codes.
YES. Bad fuel pump pressure can cause that problem too.
Assuming the fuel filter has also been replaced, a bad distributor cap and or wires and spark plugs could do that also.
sounds like timing is a bit off!!
If you have replaced plugs and wire most likely one of your coil pack usually run about $50
Water in fuel system, bad wires , distributor cap, spark plugs, theres a lot of things that could cause this problem, Is your check engine light on, If so you need to have the engine scaned to see what the code is and then go from there. Hope this helps.
