stalling

Hi, I have a '94 chevy Lumnia Van 3.1,The van starts up and runs good for about 15-20 minutes then it will stall. If I try to start it up again it starts and idles util I try to put it in drive then it stalls. If I let it sit for an hour or so it willstart up and I can drive it, but then the whole thing starts all over again. Anyone have any ideas what could be wrong.

could be an ignition control mod
or crank sensor going bad
i have a lumina car so i don't know exactly
how your motor is configured

on my car the icm is on the front bottom of engine block
between starter and exhaust manifold

crank sensor is in the back of the block in the middle
near top of the oil pan

both of these can be tested at autozone
if you get them out

becareful taking out crank sensor
they some times break

Will it rertart with a spray of carb cleaner into the intake, this will at least eliminate no spark problems.

my lumina died when i spraid carb cleaner down its throught

it is your ICM, once your car heats up it starts acting up. mine did the same exact thing. if it was the TPS you would see that its cracked and it would throw a code. also if it was the CPS it would do it not only when warm, but cold also.

pull out your Ignition control module. i got one from Autozone for $108 after tax, lifetime warranty. car has never ran better.
