Starts & Runs Great Until Hot Outside

[dcoydad]

I have a SC300 with the GTZ single turbo conversion. It runs great but has developed a problem that is getting worse. Sometimes when things get hot the engine dies. The started and all ectrical lights work but the car stops getting ignition or possibly fuel. Sometimes it seems to be starving for fuel. Usually if I keep the rpms up it will get me home but if I let it get loo low it dies again. When it dies it normally will not start immediately. On a couple of occassions I have thumped around on the fuse box undet the hood and the car starts and runs again for a while. I think something electirical is overheating or getting weak. I hate to start changing parts without a reasonalble place to start. Has anyone had simuliar problems? Thanks
