Lt1 engine stops running after approx. 15mins or so of driving time. It will turn over but not fire. I will start after sitting for awhile.Its not overheating and it doesn't give any warning. the optispark was replaced about 3000 miles ago,recently replaced spark mod and coil. Not sure where else to look. could use some help since its intermintent.
