91 560 SEL stops Running

[corvetkid]

I have a 91 560 SEL that the engine stops running intermittently. This just started this week and has happen three time. I'll be driving and all of a sudden the engine stops. If I wait about 15 mins it will start again. It just happen again today and even after waiting about 45 mins is wouldn't start. I had it towed home, and sure enuff as soon as the tow truck drove off it started. When the engine stops it still turns over fast enuff but won't start. So its not getting spark or fuel is my first though.

Any ideas where I should start looking at?


Thanks Bob
