for the past 2 weeks my truck has been dying on me at random, i have replaced fuel pump/filter, tps, plugs. cleaned air filter, idle control valve, fixed an exposed wire on my crankshaft sensor. now (twice so far) when it has died it sounds like it is releiving pressure, directly below me, the only thing below me is the fuel filter that i know of. WTF???

maybe try having the ignition control module tested at least 5 times so you can see if it's good or not when it's hot..?

they have a machine, you'd have to take it off and run it up there

When an engine suddenly quits running, but then starts again and runs normally. The cause may be the loss of an important sensor signal such as the crankshaft position sensor signal (distributorless ignition systems) or the ignition trigger signal (engines with distributors). GM HEI ignition modules are prone to failing when they get too hot - especially if someone replaced the module and forgot to apply the heat sink grease underneath to prevent the module from overheating.
Run the engine with a blow dryer aimed at the ignition module.

the ignition module is the heatsink finned type thing on the bracket with the coil.
