could it be the ecu.....it runs fine when first started but once it heats up it stalls and wont start back up...i can let it set for a cuople of hours go back out and it will start right back up until it gets warm...then stalls again

Well thats not usually the cause for a heat problem but you never know. When cold you could try blowing on the ECU with a hair dryer to see if that heat makes it fail. Also look inside ECU to see if you have any leaking capacitors or burned areas.
