I had something like that happen...
Turned out that i had bad spark plugs, a bad coil lead, which killed my HVC which may have killed the ignition module.

to top it off i had just switched to lpg.

finally got it fixed though.

paid $30 to a shop to have the compression tested, Got a free tow ( thanks to the wife for the AAA ) and bought a spare old skool dizzy with no ign module and a spare CDI module and coil and a replacment coil lead.

so it cost about $200 and a week or more of fooling around.

it's kind of scary when you can't get any help because your car is too custom.
