I had the same problem, not sure if this will help but mine was caused by a cracked spark plug.. like you said it sounded like it was gona die and kinda sputtered.. not sure if that is it but i would check the spark plugs

could this be the oil pressure unit at the top back of the engine.. i read it will get old and kill the power or something to the fuel pump...

#470 of 486 Bad ignition wire by duntov

Mar 24, 2012 (3:34 am)

Just one ignition cable can cause the ICM (Ignition Contriol Module) to deliver the wrong firing sequence or even stop working until the cable is removed from the source of the ground. For example my friend replaced the spark plugs on my S10 Blazer and did not put the ignition cables properly in the wire looms. One of the cables lay against the hot exhaust manifold and burned through the insulation. When the conductors grounded against the exhaust manifold, it caused the ICM to stop working intermittently but when the wind blew the ignition cable off the manifold, the engine started running properly again. I found the bad cable and put all the cable through the wire looms and the engine never misses a beat. I have since replaced the ignition cables with the correct AC Delco ignition cable kit. If you have lost any of the oroginal wire looms, a new wire loom kit is available. AC Delco 8073 (GM 12073948) for $4.50. Dorman also has the same looms in various assortments of 2, 3 and 4 wire looms under part numbers 40283, 40284, 40286, 40281, 40288, 40289, 40291, etc. If Dorman went to the trouble to manufacture that many different GM wire looms / holders, they must be important parts.
 
  
It is important to make sure the ignition cables are in the wire looms and are in good condition. Ignition cables should be replaced at 30,000 mile intervals along with the distributor cap and rotor. GM sold individual ignition cables for customers who found one or two damaged cables. However, GM stopped that practice and now GM only sells complete ignition cable sets, just like the all the aftermarket suppliers.

Have had problems with this blazer since August. I have had it for 9 years and no problem until August 2011. Would go dead when slowing down. Have changed spark plugs and wires, rotor and cap, cam position sensor, thermostat, fuel filter, idle air control, ignition coil, and just last month it would go dead and ses light would flash. Had it towed and they changed the ignition control module. Ran great for about 1 1/2 months. Saturday night drove it and noticed it hesitating during acceleration. It stopped doing that and I got to the store. Got back in 15 minutes later and it started great and ran great. Did not drive it Sunday. Monday morning it would not start. It seemed to try after a couple of tries and just sputtered out. Checked fuel pressure. 60 psi with key on and pump priming. When pump cut off, dropped to 55 psi immediately. So, I have no idea what could be wrong now.

Well, while waiting for my husband to get home so we could check the pressure again and see where it is 10 minutes after priming, I decided to try to see if it would start. IT STARTED RIGHT UP!! What's up with that. Oh, I should have mentioned, I was rear ended about 1 month ago. No apparent damage. Wonder if that tripped something. I am baffled!

I have recently had the fuel Filter replaced and it runs just fine now.

I just had my 99 blazer stall out and would not start at all. Still had power just wouldnt turn over. I ran a scan for fun and it came up the crankshaft position sensor. Just something to check out, hope it helps.

check the inline fuse locate in the alternator wire that runs under the battery tray, mine was doing the same thing, and i replaced everything i could think of , and it was the fuse....a lot of money spent for a $2.00 inline fuse...lol...
