Really a little more info like year and engine would help. "We live in a time when intelligent people are being silenced so that stupid people won't be offended".

I just went thru something similar and last evening found the root cause to a an intermittent connector to the distributor. Apparently the thermal expansion as the motor got up to temp, combined with the vibration of the motor running would cause the connection to open, killing the pulses from the distributor to the ignition box.

It would start right back up but die if I put it in gear. Let it cool down and repeat. I replaced the coil and it fixed the problem. ., (O O {]{]{]\|\|[}[}[} O O) 1971 Plymouth 'Cuda 440-6 {\|\|O\|\|} 2000 Yamaha V-Max (O O [========= SRT] O O) 2011 Dodge Challenger SRT 392 .

I had problems with the floats on my old Holley and they would routinely stick and flood itself out after some spirited driving. 68 Valiant 408 69 Charger 318 69 Cougar 351W 70 Torino GT 351C 71 Country Squire 351W 71 Road Runner 440+6 71 Satellite sedan 318 73 Duster 318 73 Challenger 383 77 Grand Prix 455 83 Malibu 9C1 383 84 Delta 88 403 87 Grand National 96 Ram 360 09 Crown Vic 10 Challenger R/T M6 15 Challenger Hellcat M6
