98 blazer problems stops running w/out warnings

Does anyone know why my 98 blazer stalls out? I can start it right back up and then it does it again after a few min. No check eng lights or anything. Please help!

When was the last time you changed the Fuel filter on it.
How many miles does the truck have on it?

I've only had it a few days, so I haven't changed it. I've read on here that the ignition switch goes out in th 97 and can have the same symptoms. I'm wandering if it is the same with the 98?

Is there anyway you could test those Ignition Switch Module?

First thing check for lose of spark or fuel or both.
If you have good hot blue spark to all plugs when it quiets
A good fuel pressure gauge check would be in order.

Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
Later V6 and V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel.
Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.
Post back fuel pressure readings.
